Changes in Upfront and Issue won't Save

I've been trying to use Issue, but whenever I hit undo, even if I save after every step I take, it refreshes the page to starter home page at beginning of the theme. ?!?!? I keep losing all of the changes I made. Not the color scheme and font I added to the theme options, but anything I deleted on the page, changed the background color for - gone. I've tried and lost work now multiple times.
