Question about 7.x-2.0 concerning admin/config/people/accounts/display

Hi all, I've been reading through various postings on seemingly minor issues with DS through various sites/forums. I have one question regarding the 7.x-2.0 build. When attempting to "manage display" of the user, the display ends up broken. All other tabs, links, etc seem to be working.

At first, I thought it was an overlay issue, but after turning it off, clearing cache, etc. It still performs the same way. Then I thought it was possibly an issue with the Field Group module, which was disabled, cache cleared, and server even restarted. Still the same issue.

Anyone have a clue what could be causing this? It was working at some point, but several modules have been installed since attempting this action. Disabling each contrib module one at a time has not produced any results.

Attached is a screenshot where the admin theme has been wiped unlike everything else, and the display does not render.

I would appreciate any help on this matter. Thank you in advance!
