I have little idea how you got the output you show. What is it? Please provide an MWE (from \documentclass... to \end{document}) that we can compile that shows your problem.

Odd pages are tight-hand pages, and often, a section heading is used as the running head. This text is simply too long, and you need a shorter version. You can use an optional short version, almost always permitted: \section[<optional short form>]{<full form>}.
