Members list "No team permissions" filter doesn't work

Does anybody else have a “No team permissions” option in the Team permissions filter of the Members list, together with a clear number indicating, supposedly, how many people have no team permissions, but when you click on it, it says “No members to show”?

It’s baffling to me. All the other filters are set as “All”. I expect to see what are those 21 people (it would be mega useful). I have asked a few times to the support team who either don’t seem to understand me, or assume this is expected behavior.
