This bug can happen when you adjust the level of your character and try going higher than level 60. What happens is the statistics kind of wrap around back to level 1 and wonky things start happening. Especially when playing the vanilla game and not using a mod that adjusts the level cap.
The work around is to recreate the character and to only use the Set Level option and not try to adjust using the increments when the character is level 60 already. Also do not set character level to 0, only use numbers between 1 and 60.
