How do I avoid repeated primary and secondary groups?

[BlackShot 7]

Hey folks,

I'm using the Donations plugin to assign the "Donor" group as the primary group for regular members. For other members, like mods and admins, I'm assigning it as a secondary group.

But what's happening is that regular members are getting "Donor" both as primary and secondary groups, which duplicates some visual things like titles.

Is there a workaround for this? Or a way to make the forum check for members that have  equal primary and secondary groups and remove the secondary group automatically?

Thanks!

I could assign the Donor group as a secondary group only, for all members, but then the group formatting wouldn't apply to them. Maybe I'll make a topic about that.
