I still cannot change my masteries

I haven't been able to change my masteries for a couple of days now.

Everytime I save them whether it's before the game of during the lobby they just change back to the old settings when I save them and return to see if they changed.

The only thing I can do now is delete a mastery page create a new one fill the masteries hit save and wait in the mastery section for the game to start.
