Cisco ASA 5505 won't let me update password

[Apple Of Sodom]

The title says it all. I'm using the GUI and when I try to update the password for my PPPoE account, it states the account already has a password and it defaults it back... any ideas how to force a password update?

Got it figured out. Gotta use the cmd line interface to remove the usernames. Stupid.
