Either wait for an update and hope this gets fixed (unlikely since there hasn't been much response here), or delete your character and start over.

I have found a duplicatable bug that screws your character to the point of requiring deletion. You must first complete the story mode (only on normal, higher difficulties don't need to be done, you need access to all stages.) At this point, you can play the stages in any order. After that add a new character to the party, that has not played the final set of areas (hook mountain massacre). If you play the areas out of order, and play the 4th stage last (battle at the dam), once the after battle sequence occurs, you will choose a power for beating e dam, then you will choose a role for beating the scenario, then you will go back to choose a second power as a scenario reward. However, you can't select the power. You can make the game playable again by deleting that particular game save from the menu, however, this leaves the affected character with stages 4.1, 4.2, 4.3, and 4.5 complete. Any replay of 4.4 will once again create this problem. If you play those 4 stages before the dam, it becomes impossible to ever choose a role.
