从个性化 Montpellier beamer 中的框架脚注中删除标题

Question

我正在准备使用 Montpellier beamer 主题的演示文稿。我尝试个性化标题框以添加页脚。以下代码的问题是标题同时出现在标题栏和页脚中。我希望它只出现在标题栏中。那么请问我该如何从我的个性化 Montpellier beamer 页脚中删除标题并将其仅保留在标题中？

    \documentclass[xcolor={dvipsnames},10pt]{beamer}
%
\useoutertheme{infolines}
\usetheme{Montpellier}
\setbeamertemplate{footline}[infolines]
%
\setbeamercolor{footlinecolor}{fg=black,bg=cyan!40}
\setbeamercolor{title in head/foot}{bg=PineGreen,fg=yellow}
\setbeamercolor{author in head/foot}{parent=footlinecolor}
\setbeamercolor{date in head/foot}{parent=footlinecolor}
\setbeamercolor{separation line}{bg=cyan!40}
%
%
\setbeamercolor*{structure}{bg=PineGreen!20,fg=PineGreen}
\setbeamercolor*{palette primary}{use=structure,fg=yellow,bg=structure.fg!70!gray}
\setbeamercolor*{palette secondary}{use=structure,fg=yellow,bg=structure.fg!65}
\setbeamercolor*{palette tertiary}{use=structure,fg=white,bg=structure.fg!75!black}
\setbeamercolor*{palette quaternary}{fg=orange!30!yellow,bg=black}
\setbeamercolor{section in toc}{fg=black,bg=white}
\setbeamercolor{alerted text}{use=structure,fg=structure.fg!50!black!80!black}
\setbeamercolor{titlelike}{parent=palette primary,fg=structure.fg!50!black}
\setbeamercolor{frametitle}{bg=gray!10!white,fg=PineGreen}
\setbeamercolor{title}{fg=yellow,bg=PineGreen}

\usepackage{tikz}
\addtobeamertemplate{headline}{}{%

\end{tikzpicture}

我假设您想从所有框架的脚注中删除文本“标题”，同时仍将脚注的中间部分保持为绿色。在以下 MWE 中，我定义了一个新模板，并通过使用而不是像在参数中那样放置命令footline来更正字体。最后，我还在作者字段中使用了 来摆脱与 - 相关的警告。title\setbeamerfont{title}{size=\small, series=\bfseries}\smalltitle\texorpdfstringhyperref
