I’m trying to generate a table of content that doesn’t include empty pages in the page count. In my document, LaTeX automatically inserts empty pages when a new chapter begins. Because the new chapter should always start on the right side of the book/dokument. However, LaTeX counts these empty pages in the table of contents, which I want to avoid. You can see the problem on page I and III in dokument or simply in the picture. I’m looking for a solution to ensure that only pages with actual text are included in the page count.

I use this template file on overleaf:

Thank you for your help. I’m really struggling with this issue.

thispagestyle{empty} – but it did nothing.
I changed the type of the dokument but afterwards i was not able to have a different format for left and right pages.
