Scrivener driving me crazy (again!)

So I’m trying to export my manuscript to my tablet so I can review it and see what need fixing but everything I compile to mobi Scrivener messes up the menu and adds random text from random chapters.

This is why I gave up on it. As the manuscript is stuck in it (for the moment) i need to work out what is going wrong!

Guess what the problem chapters are?

Yup it’s the duels!

Edit: After half a pint of Japanese Beer and with my nephew curled up on top of me I found the issue was down to some lables that I hadn’t set!
