The produced toc file has the following content:

What is causing the problem and how do I resolve my issue?

[Kreuz Elf]

I think the problem lies in

Code: Select all

\AtBeginSection{\frame{
%    \frametitle{Content}
    \tableofcontents[currentsection]
}}

Try deleting that and instead you may use \tableofcontents[currentsection] later on in you document.

That resolves the problem, thanks. I still don't understand why the problem crops up, is this a compiler bug? Also, How do I change the title of my question? The current one is not descriptive.

[Kreuz Elf]

sry, I'm not able to answer your follow-up question. Maybe someone else will be.
