Hi,

welcome to the forum!

That can be caused by a \chapter (re)definition in your document class, your preamble, a loaded package, or in format.tex. All of this is missing here, feel free to add it.

Thank you stefen, I have updated the post with preamble. There is not re-definition in the document class. I guess the problem might me in the loaded package. Thanks again!

[Stefan Kottwitz]

It is caused by this line:

\renewcommand{\chaptermark}{\markboth{}{}}

Remove it, or make it another way.
