我在撰写论文时遇到了以下问题。我在 Overleaf 上使用包含“fancyhdr”包的 Latex 模板，用于在页面左上角添加章节标题（此处为案例项目：https://it.overleaf.com/1433821482pvjkxhmrvwnh)。但是，每章的最后一页都有页眉，其中报告了下一章的名称。不幸的是，我不知道模板的确切名称，因为几年前我的一位同事给了我。顺便说一下，这是主 (.tex) 文件：
% Set up the document
\documentclass[a4paper, 11pt, oneside]{Thesis} % Use the "Thesis"
%style, based on the ECS Thesis style by Steve Gunn
\usepackage{placeins} % put this in your pre-amble
\usepackage[square, numbers, comma, sort&compress]{natbib} % Use
%the "Natbib" style for the references in the Bibliography
%% ----------------------------------------------------------------
\begin{document}
\frontmatter % Begin Roman style (i, ii, iii, iv...) page
numbering
\begin{titlepage}
\begin{center}
\textbf{Ph.D. DEGREE IN ...}
\end{center}
\end{titlepage}
%% ----------------------------------------------------------------
\setstretch{1.5} % It is better to have smaller font and larger
%line spacing than the other way round
% Define the page headers using the FancyHdr package and set up for
%one-sided printing
\fancyhead{} % Clears all page headers and footers
\rhead{\thepage} % Sets the right side header to show the page
%number
\lhead{} % Clears the left side page header
\pagestyle{fancy} % Finally, use the "fancy" page style to
%implement the FancyHdr headers
%% ----------------------------------------------------------------
\lhead{\emph{Contents}} % Set the left side page header to
%"Contents"
\tableofcontents % Write out the Table of Contents
%% ----------------------------------------------------------------
\lhead{\emph{List of Figures}} % Set the left side page header to
%"List if Figures"
\listoffigures % Write out the List of Figures
%% ----------------------------------------------------------------
\lhead{\emph{List of Tables}} % Set the left side page header to
%"List of Tables"
\listoftables % Write out the List of Tables
%% ----------------------------------------------------------------
% End of the pre-amble, contents and lists of things
% Begin the Dedication page
\setstretch{1.5} % Return the line spacing back to 1.5
\pagestyle{empty} % Page style needs to be empty for this page
\addtocontents{toc}{\vspace{2em}} % Add a gap in the Contents, for
%aesthetics
%% ----------------------------------------------------------------
\mainmatter % Begin normal, numeric (1,2,3...) page numbering
\pagestyle{fancy} % Return the page headers back to the "fancy"
%style
% Include the chapters of the thesis, as separate files
% Just uncomment the lines as you write the chapters
\input{Chapters/Chapter1}
\input{Chapters/Chapter2}
\input{Chapters/Chapter3}
%% ----------------------------------------------------------------
\label{Bibliography}
\lhead{\emph{Bibliography}} % Change the left side page header to
%"Bibliography"
\bibliographystyle{unsrtnat} % Use the "unsrtnat" BibTeX style for
%formatting the Bibliography
\bibliography{Bibliography} % The references (bibliography)
%information are stored in the file named "Bibliography.bib"
\end{document} % The End
%% ----------------------------------------------------------------
每个输入章节都以这些行开头：
\lhead{\emph{Chapter number "x"}}
\chapter{Chapter number "x"}
这不是一个可行的示例，因为缺少文件 .sty 和 .cls（以及输入章节）。但是，如果我编译它，在第 3 页（第 1 章末尾）我已经看到下一章的标题，但它在下一页。我是否应该提供其他信息来帮助我解决这个问题？谢谢
