Export to Word "eats" parts of document

Hello,

I am currently writing my thesis and I love Scrivener for this task. Today should’ve been the big day - I tried to export it. As I need footnotes, not endnotes I have to export it to docx, not PDF in the first place. After exporting my file I noticed that several headings and subheadings were missing, as well as several pages. I definititely have selected all parts and it looks very arbitrarily to me.

Any ideas?

Thank you very much!

Selecting is one thing, but ticking whether titles and/or text should be included is another thing to check.
