Weapon attachment bug

When equipping any dlc/beta weapon variant, not all of the attachment changes do not stay. For example, when equipping the SGX Dominion variant and removing the pre-attached laser, the laser will reappear in game and essentially undo itself. The same goes for the M2010 ESR Drop Shadow and trying to remove the Range Finder left accessory. It feels extremely limiting to be able to remove it in game and the menus but when transitioning from lobby to game or game to lobby it removes those customizations.
