Sorry to respond to an old message if that is frowned upon, but no one replied. I had the same problem today and had a hard time finding the answer. It looks like this is our issue:

In short, the game is confused because you are two classes via some sort of cheat.
Yes, I cheated with the Xbox level up glitch (after finishing legit). I am a Jedi Guardian/Jedi Consular. I will need to play some more on another planet so I can get a Prestige Class and wipe out the Jedi Consular. As warned at

the game will freeze if you try to get a prestige class and you don't have a level up. So I'll need to play until I'm at level 15, going on 16.
Hope this helps.
