I have already successfully changed the \captionsetup{} of my document to a different format provided in the code below. However, I need to come back to the original \captionsetup{} but it does not clear the previous specification and come back to default. I need help with this. Below is a minimal working example (MWE) that should be working on Overleaf, but it doesn’t.
\documentclass{article}
\usepackage[spanish]{babel}
\usepackage{caption}
\usepackage{fontspec}
\setmainfont{Arial}
\begin{document}
\begin{figure}
\centering
\caption{A default caption.}
\label{fig:default}
\end{figure}
% Change the caption setup
\captionsetup{labelfont=bf, textfont=it}
\begin{figure}
\centering
\caption{A custom caption.}
\label{fig:custom}
\end{figure}
% Clear the caption setup
\captionsetup{}
\begin{figure}
\centering
\caption{Back to default caption.} % This caption stays the same as the previous one
\label{fig:backToDefault}
\end{figure}
\end{document}
I am using XeLaTeX to compile the project taking into account the need of it to use Arial as main text font.
