"Require new topics to have tags from tag groups:" not honored

I have “Require new topics to have tags from tag groups:” enabled, but I can can still create new posts without choosing a tag from the designated group.

When I go to create a post, it shows options for a different tag group to choose from.

What would cause the required tag to not be honored and why aren’t they showing up in the list first to choose from?

Those rules don’t apply to admins and moderators

Ah, I didn’t realize, thanks.
