Position wont change

I am having the same problem.  Played my first season, was moved to center, finally, right before the playoffs.  Won the cup and every individual award imaginable.  Started the preseason as the center and was killing it.  Suddenly moved back to left wing and the center I’m playing with is losing over half of his face offs.  Hugely frustrating.  Thought of asking for a trade, but I like the team I’m on.  No way to change it and it’s making me want to quit the game.  Please rectify this, it makes no sense to frustrate players when they are playing against the computer.
