Forum Users Color not working correctly, registered message showing to all sub
 

Now that I setup all my subs as "additional usergroups" and not primary it seems when they buy they still stay a registered user as primary. So messages I setup for registered users keep showing even after they become a sub. Also it seems everyone that purchases won't turn a different color for users online. They all stay the registered user color.

How can I make it so that primary usergroup: which is registered will switch over to the secondary usergroup: sub when they purchase?

Some people buy more than one sub and nothing is working correctly now. :(
