This first problem has been going on since FIFA 11, in the player edit menus - you still can't make a player a CM, RW,LW, LWB or RWB. You could in FIFA 11 and earlier, why take it out, put it back in EA.
But most significantly you can't actually edit a player in the game who is born in 1999 or later without them aging to their 50's, it's ridiculous. For example I wanted to actually be able to use Reiss Nelson in my Arsenal career mode so I increased his useless 35 STAMINA up to 65 so he can actually play more than 60 minutes without collapsing, and he became 57 years old and retires the season after. It was also like this in FIFA 17 and I have no idea why this hasn't been fixed by EA, and I haven't seen anyone bring this up.
It's not like it's hard to make these changes.
