Two quick things I notice. No idea if either will fix.
When creating actual group names for ULX, or editing "group" fields for Uteam., always use lowercase. ForumMembers should be forummembers.
In UTeam.txt "Name" fields, _then_ they can be named any case you like them, but always use lowercase for groups.
In your Uteam.txt file, the 'R' color paramter for the name = Petty officer, group = user area #17 is blank.
Not sure which or if either will correct it, but it's a start.
