It had to do with when ubb added the global moderator feature.
Where it did not exist before.
So using the dbase group id
1 admin
2 moderator
3 user
4 guest
Became
1 admin
2 global moderator
3 moderator
4 user
5 guest
Then Rick only included the correct importer for the previous version that did not have it to the current version at the time that did.
So as you can see a user became a mod
a mod became a global mod
In your case it appears moderators are a member of the moderator group but you never assigned a actual moderator.
The nine global moderators were probably moderators at the time of the upgrade.
I can't believe you lived with this for so many years.
