Auto subbed my 2nd string RB on my D Line….

Trying to use wear and tear system, which has so many bugs. To begin, even if you pull a player due to injury, somehow the player remains in the game. I am playing a CFP first round game - 3rd and 7 after my 90 DT gets hurt. I say fine, I have an 85 DT that will sub in, no issue. I go and pick my play, and notice that instead of my 85 OVR D Lineman subbing into the game, my 2nd string RB is now at D Tackle! They of course run the ball and get a first down, possibly dealing the game! This then happened again and it subbed my starting RB! Gotta be fixed!

This makes no sense! At no point in substituting should this even be possible!
