Good day, I've been having a lot of trouble getting Latex to output a normal figurename. For some reason, each caption reads "?figurename? x" (with x being the number of the image), despite me not specifying any \figurename. I've tried changing stuff around but it doesn't seem to work.
This is my preamble:
\documentclass[smallextended]{svjour3}
\usepackage{mathptmx}
\usepackage{helvet}
\renewcommand*{\proofname}{proof}
\renewcommand{\familydefault}{\rmdefault}
\usepackage[T1]{fontenc}
\usepackage[latin9]{luainputenc}
\usepackage[a4paper]{geometry}
\geometry{verbose,tmargin=3cm,bmargin=3cm,lmargin=3cm,rmargin=3cm,headheight=2cm,headsep=0.5cm}
\pagestyle{empty}
\setlength{\parskip}{\smallskipamount}
\setlength{\parindent}{0pt}
\usepackage{babel}
\usepackage{float}
\usepackage{textcomp}
\usepackage{pdfpages}
\usepackage{amsmath}

\begin{document}
\title{some title}
\subtitle{some subtitle}
\author{Me}
\maketitle
\section{Introduction}
\label{intro1}
\input{input_containing_pictures.tex}
\begin{figure}
\begin{centering}
\includegraphics[scale=0.5]{img/resnetplot}
\par\end{centering}
\caption{Precision-Recall\label{fig:Curves-1}}
\end{figure}
\end{document}
Am I doing something wrong?
In the end I managed to find the error: somewhere in my inputs a bunch of rogue \selectlanguage{english} kept changing the default language for the article. The language options couldn't decide which \figurename was the correct one so it kept throwing me a ?figurename?.
