Captain Bernard training glitch

I was training with Bernard a few times and learning the new skills you get from him like combos and master strike. But after a few failing attempts to learn from Bernard…his character glitched in the strike pose. He walks around in the strike pose and fights in the strike pose; without seeing his arms move.

On console PS4.

Go to your bed and make a save. Restart the game and load this save. After reloading he should be fixed /fight normal. (This workaround worked for me at PC)
If Bernard is stuck in strike pose don´t start another fight with him!
There is no progress in his lerning leason and you can´t leave the arena. So you lose time and must reload…
