QA Ticket, DMR GRT - Chemical doesnt change nor save loadout in game

Heres a visual of me changing the load out, but I already own the gun fully from battle pass, im not sure if that has anything to do with it? 

In the video below, Player has obtained the new weapon from the battle pass so I was able to change loadouts. VS before when I didnt have it, but im almost positive that you could have changed it before hand? Video below is showing that its working as intended being able to change the special skin.
