This is a minor bug in the display of the tabs when editing the profile with version 2. I have attached two screen shots. The first is from viewing the profile, and shows the nicely displayed tabs of version 2. The second screen shot shows the editing of the profile, and what the tabs look like. They appear as oddly spaced buttons, not the nice tab display found in the viewing of the profile or in the registration pages.
I have checked and don't have any template overrides in place.
As I said just a minor bug. It doesn't look nice though.
