\calstable top row of 2-row thead no text

Question

I've created a LaTeX (xelatex compiled) table with \cals package, specifically, using \calstable command. I'm using R's RMD file to compile LaTeX to PDF. However, I'm using two rows for a nested \thead{} command with an intermediate .tex similar to the following:

%example.tex file

\documentclass[]{article}

% package load
\usepackage{cals}
\usepackage{xcolor}

% initialize @ symbol
\makeatletter

\begin{document}

% begin custom commands
\newcommand\cellVtop[1]{
  \cell{#1}} 

\newcommand\cellVbot[1]{
  \cell{\vfill #1}}

\newcommand{\rrBoxGrantee}[1]{
  \parbox{2.5in}{\raggedright #1}}

\newcommand{\rrBoxFiveCol}[1]{
  \parbox{1in}{\raggedright #1}}

\newcommand{\rrBox}[1]{
  \parbox{0.875in}{\raggedright #1}}
% end custom commands    

\colwidths{{0.5in}{2.75in}{1.08333333333333in}{1.08333333333333in}{1.08333333333333in}}
\small
\begin{calstable}

\thead{
  \brow
    \nullcell{ltr}
    \spancontent{}
    \nullcell{ltr}
    \spancontent{}
    \nullcell{ltb}
    \nullcell{tb}
    \nullcell{trb}
    \alignC\spancontent{\vfill \textbf{Enrollees}}
  \erow
  \brow
    \alignC\cellVbot{\rrBox{\textbf{Rank}}}
    \alignL\cellVbot{\rrBox{\textbf{Grantee}}}
    \alignL\cellVbot{\rrBoxFiveCol{\textbf{Target}}}
    \alignL\cellVbot{\rrBoxFiveCol{\textbf{Actual}}}
    \alignL\cellVbot{\rrBoxFiveCol{\textbf{Percentage of Target}}}
\erow}

% begin multiple rows [...]
% repeat code for the below row until page break occurs (~30 rows)
\brow
  \alignL\cellVtop{0}
  \alignL\cellVtop{\rrBoxGrantee{Grantee A}}
  \alignL\cellVtop{0}
  \alignL\cellVtop{0}
  \alignL\cellVtop{0\%}
\erow
% end multiple rows [...]

\normalsize
\end{calstable}
\pagebreak

\end{document}

With, [...] representing excluded text for brevity.

However, when compiled, any table that runs to a next page is missing the header text of only the top-row of the \thead. The strange thing is that cell formatting is correct, just no text. It does seem that when there are no calls to \nullcell{} and \spancontent, that the columns are repeated as expected. However, I need the top header with "Enrollees" included to be merged as pictured below.

Am I missing a setting for printing both \thead rows or is this a bug?

P.S. I've confirmed that the example.tex file, above, can be compiled to .pdf via the following command in command prompt: xelatex example.tex

The text is not lost, it's just too far right off the page. Spanning setup is a complicated thing which can go wrong. For each span, there should be one and only one "spancontent", but your code has several. To fix:

\thead{
  \brow
    \nullcell{ltr}
    %\spancontent{}  % FIXED
    \nullcell{ltr}
    %\spancontent{}  % FIXED
    \nullcell{ltb}
    \nullcell{tb}
    \nullcell{trb}
    \alignC\spancontent{\vfill \textbf{Enrollees}}
  \erow
  \brow
    \alignC\cellVbot{\rrBox{\textbf{Rank}}}
    \alignL\cellVbot{\rrBox{\textbf{Grantee}}}
    \alignL\cellVbot{\rrBoxFiveCol{\textbf{Target}}}
    \alignL\cellVbot{\rrBoxFiveCol{\textbf{Actual}}}
    \alignL\cellVbot{\rrBoxFiveCol{\textbf{Percentage of Target}}}
\erow}
