我正在使用 overleaf 撰写报告。
我使用了我大学制作的模板。唯一的问题是，当我有\subsection{Implementation} Then 时，它显示为：
0.1 implementation
这里前面的零确实让我很烦。
我有一个如下所示的配置文件

我的文件顶部main.tex，也就是我的所有内容，如下所示：
\documentclass[fleqn,10pt]{olplainarticle}
\usepackage{listings}
\usepackage[colorlinks]{hyperref}
经过自我搜索，我发现配置文件底部的这一行似乎应该更改：
\setcounter{tocdepth}{3}
但是现在我尝试改变这条线，或多或少地用了所有我能找到的数字和输入的排列，但似乎都没有任何区别。
我如何从 1 开始计算我的部分？从而避免以零开头？
