Using \@author Latex messes up figure captions

I am using the \@author command from the authblk package on Overleaf to list chapter authors per chapter without creating a new title page every time (example below). This works, but as soon as I include the \@author command, all figure captions in the chapter get misplaced. Does anyone know how this could happen? The author command and figures are completely unrelated as far as I'm aware (but apparently not), so I don't even know where to begin to try and solve this...

Or alternatively, does anyone have suggestions for another way besides \@author to show the authors and affiliations per chapter without using \maketitle?

This is what happens on any page that has a figure: enter image description here

Solution

  • You can avoid the problem by placing \@author in some kind of box, e.g. a minipage:

    \documentclass{book}

\usepackage[noblocks]{authblk}
\usepackage{graphicx}

\begin{document}
    
    \author[1]{Author 1}
    \affil[1]{Affil 1}
   
    \noindent\begin{minipage}{\linewidth}
        \makeatletter
        \@author 
        \makeatother
    \end{minipage}

    Main text of chapter, with figures.
    \begin{figure}[h]
        \centering
        \includegraphics[width=.8\linewidth]{mouse.jpg}
        \caption{This is a test caption}
        \label{fig:mouse}
    \end{figure}
    
    test


\end{document}
