Automatic substitutions/tactical changes on career mode

Hi! I love playing career mode on Ea FC 26, and I always use the «tactical view» option when playing a game. But, every time half-time comes around, I experience either an automatic substitution, or a tactical change. Sometimes I can’t even change the tactic back to the way I want it. This is super annoying, when they substitute my best player for a worse player that doesn’t even play in that position. I have gotten some tips, like turning off the suggested subs and turning «watch full match intro» to always, none of those has worked. This has been a problem for two years now, and this has to be fixed before I go insane. I play the game on a ps5, and everything is updated to the newest version, nothing should be a problem with the game. 

Thank you for reading, I would love this to be fixed at some point, and if anyone has any tips, I’ll gladly listen!
