My formation subs will not save on franchise (offline)

i spent all day going through all auto subs and auto formations for every single team. And it just isn’t saving for some reason. I have simply just tested it by subbing in a running back and backing out of the formations tab. when i go back its right back to thr default formation subs. What do i do? why is madden so incompetent at every single turn. why do i put myself through this senseless torture?
