After a bit more playing around, mine seems to work just fine in both directions. That is, if I change my profile then my dashboard changes to match, and if I change my dashboard then my profile gets set too.
Maybe yours has gone a bit wonky. You could try setting your profile to, say, 'Advanced', then log out, log back in, see if it remembers, and then set it back to 'Beginner'. If that doesn't work, it's probably time for the tech support people to go and hit it with a stick.
