Low Homura Weapon on Corsair

Description of the bug: (optional screenshot/video): The Homura's Shield cosmetic on corsair abilities ends up looking very weird (ie. the wrong visual with certain abilities).
What is supposed to happen?: A gun skill is used, the machine gun visual should appear. Instead, a golf club is seen shooting bullets. As hilarious as it is, since there's almost no gun cosmetics in the store I'd like this one to work as intended.
Where did you find and/or notice this bug?: Immediately after buying it.
A step-by-step guide to re-producing this bug (optional): Equip Homura's Shield over a gun, fire (regular fire, rapid fire, recoil shot all produce the same golf club, just to name a few)
Extra information (optional):

 

Here's a screencap of what it should actually look like. If I regular attack, this will show up briefly before swapping out to a golf club.
