%%%%%%%%% END OF PREAMBLE %%%%%%%%%%%%
\begin{document}
\setlanguage{greek} %% this is to activate greek hyphenation
\chapter{Introduction}
\chapter{Related Work}
...
\begin{appendices}
\chapter{Μοντέλο}
\end{appendices}
\end{document}
结果是：
有人知道为什么这个框会出现在字母 A 旁边吗？我该如何将其删除？
答案1
我已删除以下命令：
\usepackage{xgreek}，这导致了问题\setlanguage{greek}
现在该框已从附录中删除，但不影响英语和希腊语之间的切换。
