Day 6 of defensive bug..

UPDATE: I have now uninstalled the game and reinstalled it, and it did nothing.
Ultimate team - Day 6 of anytime I am on defense whether it’s a challenge, head 2 head, or squads, when I switch to a player besides defensive line, whoever I switch to either dives automatically or freezes and cannot be moved once ball is in play. This also happens on kickoff but not kickoff return. Happens on punt and punt return too. If I start off as a player in the secondary before the ball is hiked, when the ball is hiked it automatically switches to another player and either dives or freezes as well. This part has gotten significantly worse as far as switching to other players by itself. The only defense I can play is being a D tackle. This is extremely aggravating.. nothing at all happens offensively tho. Again, this is against the computer AND real players. What can I do to fix this asap? I have tried the coaching adjustments and everything and NOTHING works..
