子节的编号失败，带有自己的.cls

如何解决子节的编号失败，带有自己的.cls

不幸的是，我想尽一切办法获得各小节的编号。

\documentclass[a4paper,10pt,openright]{unibe-msc}
...
\setcounter{secnumdepth}{3} %numbering 3 levels also subsubsections,\setcounter{section}{3}
\setcounter{tocdepth}{2} % Visiblity depth in TableOfContent

该小节以下列代码出现在目录和文档中，但没有编号（请参见图片）。章节编号神秘地起作用。

简单的乳胶测试，例如使用\documentclass[a4paper,10pt]{scrartcl}时，小节编号可以正常工作。

系统：

• MacTex 2020
• MacOS Catalina
• texmaker

简化的测试文件（scrartcl VS unibe-msc）：

%\documentclass[a4paper,10pt] {scrartcl}
\documentclass[a4paper,openright]{unibe-msc}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\begin{document}

\tableofcontents

\section{Section}

\subsection{Test Numbering of Subsection with own class}

\end{document}
