Players Switching Randomly

hey, in the last couple of days when im playing rivals / futchamps / any gamemode, my players swtich randomly even tho I do not want to switch a player.

For instance, im chasing a winger with my fullback and it suddenly switching me to the midfielder or the centerback, hence ruining my defence...

I didnt change anything in the settings it just started happening few days ago and I cant play like that.

any1 having the same issue?
