I think the profile shows which group or forum you most often visit...
The first is which big board forum, the second which group, for example mine:
Favorite forum: General Discussion, 812 posts in the last 90 days (46% of total posts)
Favorite group: Gun Control & RKBA, 39 posts in the last 90 days (2% of total posts)
Ordinarily, my favorite group would be Energy and Environment, but all the recent kerfluffle with guns has both of us spending more time there than we might.
FWIW, I go to the gungeon off of the "latest threads" view and not by choice. I'm not a subscriber.
In any event, I don't think you can remove it from your profile except by not posting replies in that place for a few weeks and by posting more replies in some other group.
