Game Prep

I have no idea why when trying to adjust custom game prep (placing some players in half pads versus some players in full) it never sticks. It’s almost as if they stay on whatever I have them during the first week of preseason. After adjusting them globally or individually, they always revert back to whatever they originally had. It never saves. Am I the only one who’s been experiencing this issue? Some players I had on rest preseason week one and now I am not allowed to change them and make it stick.
