Hi David
Are you doing this through the user’s admin page?
Is it possible that the member has manually chosen ‘Member’ via their profile preferences page? It could be a matter of conflicting priorities.
I’m looking into this but it is hard to repro exactly.
It is also possible that if you had Member set to primary, that it might take a while for the database to update, but I’m not sure.
If you can wait for a while to check it to see if it is a matter of polling of the database it might help, but I’ll see if I can get more information for you
