# Biblatex creates big linebreaks if Reference Entry fills whole line

I use biblatex to cite my references. Printing my bibliography works almost as expected. If the entry's last character (in my case a dot) is at the end of a line, a big line break occurs. So a big gap is between the entry and the next one.

Here is a screenshot. The spacing between [91] and [92] is bigger, due to [91] text is filling the whole line.

I assume the big break should separate entries visually.

## Any ideas where to remove this extra big linebreak?

UPDATE: I found this snippet in my class template:

% Autoref
\def\equationautorefname~#1\null{(#1)\null} %Reference to equations in parentheses
}%


If delete these lines, the problem is gone. Does this make sense?? Seems i need an alternative to display referenced equations in parentheses like: (1).

• I would guess you have a spurious space token that ends as a line on its own but as you have shown no code impossible to guess where or suggest what to change. Please always try to give a small complete example document that shows the problem. – David Carlisle Feb 16 at 11:37

There is a spurious space in the \extrasngerman call

\documentclass[british,ngerman]{article}
\usepackage[T1]{fontenc}
\usepackage{babel}

\def\equationautorefname~#1\null{(#1)\null} %Reference to equations in parentheses
}%

\begin{document}
A\selectlanguage{ngerman}B\selectlanguage{british}C
\end{document}


The space before the % might cause unwanted space when you switch languages in some contexts.

You could try

\documentclass[british,ngerman]{article}
\usepackage[T1]{fontenc}
\usepackage{babel}
