Fancyhdr 章节/部分无法正确更新

Question

我有一个相当复杂的文档。该fancyhdr包用于格式化页眉和页脚。由于我需要多种样式，因此我定义了三种不同的样式：

\fancypagestyle{default}{
\fancyhf{} % clear all header fields
\fancyhead[RO]{\nouppercase{\rightmark}}
\fancyhead[LE]{\nouppercase{\leftmark}}
\lfoot[\thepage]{}
\rfoot[]{\thepage}
\renewcommand{\headrulewidth}{0.2pt}
}

\fancypagestyle{page_only}{
    \fancyhf{} % clear all header fields
    \lfoot[\thepage]{}
    \rfoot[]{\thepage}
}

\fancypagestyle{plain}{
    \fancyhf{} % clear all header fields    \lfoot[\thepage]{}
    \rfoot[]{\thepage}
    \renewcommand{\headrulewidth}{0pt}% Line at the header invisible
}
\renewcommand{\headrulewidth}{0pt}

%Redefine chapter by adding fancy as the chapter title page page-style
\makeatletter
    \let\stdchapter\chapter
    \renewcommand*\chapter{%
    \@ifstar{\starchapter}{\@dblarg\nostarchapter}}
    \newcommand*\starchapter[1]{%
        \stdchapter*{#1}
        \thispagestyle{plain}
        \markboth{\MakeUppercase{#1}}{}
    }
    \def\nostarchapter[#1]#2{%
        \stdchapter[{#1}]{#2}
        \thispagestyle{default}
    }
\makeatother

一般情况下，所有样式都可以访问。但是，如果我使用该default样式，章节和部分名称不会更新。我不知道为什么会发生这种情况。

经过大量调试后，我发现无法使用 覆盖“空”样式fancypagestyle。因此将模板重命名为custom_empty，现在一切正常。
