Membership + BuddyPress + Ultimate Facebook creates a registration loop

How can I register with Facebook on a site using membership and BuddyPress (for additional user profile fields only)?

There have been Several threads about this issue but I haven't found one with a clear answer. Most threads are over a year old as well.

1. Choose subscription
2. Register to site
2a. Use 'Register with Facebook' button from UF plugin
3. Form populates all auto-fed fields, click 'Register'
4. The process loops back to step 1.

How can I keep moving forward with the Facebook Registration rather than going to step 1.?
