When I go to the "Usergroups" tab in the UCP I can see all groups I'm a member of. But when I click on my username in the memberlist or in the online list the drop-down that shows the groups I'm in doesn't include some of them presumably because those groups are hidden. I would assume that even if the groups are hidden that they would show in this drop-down if I'm a member of the group.

Tracking the issue further I found that the "Founder manage only" being checked is what causes this to happen but the description to this feature clearly states that I will still be able to see the group and the members of the group.

I have attached a patch to correct this behavior when viewing profiles.
