upfront theme not allowing me to do editing.

I've used the fixer, spirit, and panino themes for some of my websites, but recently, I've been trying to switch a few sites over to one or theother of these upfront themes and I can't get to the edit page. Every time I click to "customize" I am taken to a page where I can see the page with the theme applied (the template), but none of the customization options are available.

notice the url in the screenshot and that I SHOULD be seeing the customization screen.
