beamer 标题未显示

Question

我想在图片下方写上标题，但不幸的是，当我编译文本时，标题没有出现。图片还可以，但我想在图片下方看到类似“图 1：bla bla”的内容。我在下面附上了一个 MWE

\documentclass{beamer}


\usepackage{caption} 
\usepackage{subcaption}
%\usepackage{floatrow}
\newtheorem{proposition}{Proposition}

\renewcommand{\baselinestretch}{1.2}
\small\normalsize

\newcommand{\beginbackup}{
    \newcounter{framenumbervorappendix}
    \setcounter{framenumbervorappendix}{\value{framenumber}}
}
\newcommand{\backupend}{
    \addtocounter{framenumbervorappendix}{-\value{framenumber}}
    \addtocounter{framenumber}{\value{framenumbervorappendix}} 
}


\setbeamertemplate{footline}[frame number]
\setbeamertemplate{navigation symbols}{}
\setbeamertemplate{mini frames}{}
\setbeamertemplate{itemize item}[ball]
\setbeamertemplate{itemize subitem}[ball]
\setbeamercovered{invisible}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\title{Write Title Here}   
\author{Author name}     


\begin{document}

\begin{frame}
\titlepage
\end{frame}

\begin{frame}

\frametitle{Title here}   

\begin{figure}
    \centering
    \includegraphics[width=0.7\linewidth]{Fig/myfigure}
    \caption{Write here figure caption}
    \label{fig1}
\end{figure}


\end{frame}


\end{document}
