# Odd Behaviour: Missing Chapter Title in Footer, However the Page Number is Displayed

## Problem Description

I’d like to create a footer style that would be displayed on all pages except for the page, where there is \part title and its verso page (this exception is not a problem, as it works). So I added the following code into the preamble:

\clearscrheadfoot


The actual problem is that on every odd page, only the page number is displayed and no chapter title. There is no problem with the footer on even pages.

I’d like to note that I use xelatex and currently I am trying out the KOMA-Script.

## Minimal Working Example

\documentclass[10pt, chapterprefix=false, twoside]{scrbook}

% Packages
\usepackage[a4paper, top=1in, bottom=1in, right=1in, left=1in, portrait]{geometry}
\usepackage{fontspec}            % For font definition
\usepackage{scrlayer-scrpage}    % For headers and footers (must be loaded before titlesec); also, in KomaScript, this is used instead of titleps
\usepackage{titlesec}            % For custom paragraph style of headings
\usepackage{lipsum}              % For Lorem Ipsum

% Global font family
\setmainfont{Libertinus Serif}
\setsansfont{Libertinus Sans}

% Global paragraph and line settings
\setlength{\parindent}{0em}           % Set paragraph indentation
\setlength{\parskip}{0.08in}          % Paragraph spacing
\renewcommand{\baselinestretch}{1.0}  % Line \expandafter\selectlanguage\expandafter{\cvlang}

% Part title format
\titleformat{\part}{\Huge\scshape\bfseries\centering}{}{0em}{}%

% Chapter title format
\titleclass{\chapter}{straight}% For starting a chapter without page break

\titleformat{\chapter}[block]
{\thesection\enspace}{0pt}{}[\vspace{2pt}{\titlerule[1pt]}]
\titlespacing{\chapter}%
{0mm}% How much of \titlerule line to remove from left
{8mm}% Before \titlerule
{0mm}% After \titlerule

\renewcommand*{\chaptermarkformat}{}% This is to get rid of the chapter number

\begin{document}
\part*{Test Part}

\chapter*{Test Chapter or Whatever}%
\chaptermark{Test Chapter}%

\lipsum[1-14]

\chapter*{Another Chapter to test}%
\chaptermark{Another Chapter}%

\lipsum[15-21]
\end{document}

• Off-Topic: With KOMA-Script you should not change \parindent and \parskip manually but use either option parskip (with suitable value, e.g., parskip=half) or command \setparsizes. Also you should usually use \linespread or package setspace instead of redefining \baselineskip or just remove the "redefinition", because you redefine it to its default. – Schweinebacke Apr 27 at 7:53
• I’ll look into this (and the titlesec ‘removal’) in a moment. – tukusejssirs Apr 27 at 7:59

Usually on one page is the chapter title shown, on the other page the section title in KOMA-Script.

\automark[chapter]{chapter} % <============== usually \automark[section]{chapter}


With the following complete code mwe.tex:

\usepackage{scrlayer-scrpage}    % For headers and footers (must be loaded before titlesec); also, in KomaScript, this is used instead of titleps
\usepackage{titlesec}            % For custom paragraph style of headings
\usepackage{lipsum}              % For Lorem Ipsum

% Global font family

% Part title format
\titleformat{\part}{\Huge\scshape\bfseries\centering}{}{0em}{}%

% Chapter title format
\titleclass{\chapter}{straight}% For starting a chapter without page break

\titleformat{\chapter}[block]
{\thesection\enspace}{0pt}{}[\vspace{2pt}{\titlerule[1pt]}]
\titlespacing{\chapter}%
{0mm}% How much of \titlerule line to remove from left
{8mm}% Before \titlerule
{0mm}% After \titlerule

\renewcommand*{\chaptermarkformat}{}% This is to get rid of the chapter number

\automark[chapter]{chapter} % <=========================================

\begin{document}
\part*{Test Part}

\chapter*{Test Chapter or Whatever}%
\chaptermark{Test Chapter}%

\lipsum[1-14]

\chapter*{Another Chapter to test}%
\chaptermark{Another Chapter}%

\lipsum[15-21]
\end{document}


you get the resulting pdf:

Please note the warning you got in the mwe.log file:

Class scrbook Warning: Usage of package titlesec' together
(scrbook)              with a KOMA-Script class is not recommended.
(scrbook)              I'd suggest to use the package only
(scrbook)              if you really need it, because it breaks several
(scrbook)              KOMA-Script features, i.e., option headings' and
(scrbook)              the extended optional argument of the section
(scrbook)              commands.
(scrbook)              Nevertheless, using requested
(scrbook)              package titlesec' on input line 10.

• I noted the warning, read about it on bunch of sites, however, I was not able to reproduce the same thing with Koma-Script commands as with titlesec. The most basic thing I could not achive (yet) is to set a default font family (serif, sans and occassionally math) to Libertinus {Serif, Sans, Math}. At least, this works. :) Thank you. :) – tukusejssirs Apr 27 at 6:18
• @tukusejssirs Setting of the default font is done by fontspec not titlesec and fontspec can be used with KOMA-Script in the same way as with, e.g., the standard classes. To setup a font for a sectioning command you can use \setkomafont/\addtokomafont or \RedeclareSectionCommand. If you have problems in setting up the chapter/section headings with KOMA-Script please ask another question (if no one of the already existing is suitable). – Schweinebacke Apr 27 at 7:30
• Thank you, @Schweinebacke, for the info. … Anyway, back to answer: I added \renewcommand{\headfont}{\normalfont\scshape} to change the font style from italics to small-caps regular. – tukusejssirs Apr 27 at 7:42

You could also use \automark{chapter} and and replace \headmark by \leftmark. If more than one chapter starts on the same page the last chapter will set the mark for the footer even on odd pages.
