I assume you use a custom CSS for this layout?

Maybe some pages contain a very wide table or image. This might increase the width of the usually right aligned column, and now part of the content disappears behind the toc.

A publicly accessible minimal example might give more insights. This might be a case for general CSS/HTML advice on Stackoverflow.
