Issue with alternate gun mode

So I just notice that I can’t switch to alternate gun mode on the weapons that your supposed to be able too! On the very bottom right corner, says none right where it would show to press down to switch! It does it on maliwan, Dahl, torque and vladof guns that allow you to switch! Anyone else having this issue? I’ve checked for updates and that didn’t help. Also uninstalled the game and reinstalled it just now. So hoping that works

Do you happen to have classic controls on?

My favorite thing is when you get a gun with a fixed scope or iron sights and the change mode LITERALLY does absolutely nothing because of how the gun rolled and them not really thinking this gimmick out fully lol
