I'm not exactly sure what the problem is... I am not seeing the same problem. Do you see two different types of PMs? One listed as confirmed and the other listed as unconfirmed? If so... is the problem that you cannot open any unconfirmed messages?
When I look in my inbox, I only see one type of PM (which may be because of the admin status).
Give me as much detail as you can and I'll try to figure out what the problem is.
