Scrivener Report: Epub Issues

I continue to learn Scrivener and am beginning to appreciate its subtleties and points where I need to take it outside to Word.  I compiled some documents and looked at them on my e-reader and it assumes menu items like this: Chapter 1.  I don't see any way yet to alter that. So I took to opening the Scrivener epub in Sigel and modifying the look there. For something in which appearance mattered a great deal, I'd probably go by way of Word. Or just start with it stripped of code.  I'll see what the next version is like.
