Issues Theme Header issues

I am using the Upfront editor for my site, but every time I try to edit the header, or (delete the header and add in a new one) it always comes out blank. The site looks great in the editor, I save it - but when I come out and reload the page - it's either blank or there is no menu or my image isn't saved.
I have been able to use all the other parts of the page fine, this only happens with the header. I'm saving it so that's not the issue.

I can't figure out why only this part of the editor is giving me trouble. I am trying to load in an image - but I have no idea why that would effect anything.
