Bug: Unlocked weapon slot visible for all characters

I find this one hard to explain, so bear with me.

One of my characters unlocked an extra weapon slot. Going to name this character Bob to make explaining easier.

Now EVERY character has an extra weapon slot, except... they do not. When clicking another character and checking their weapon slots they show Bob's 3rd weapon slot. When I click this weapon slot it's actually Bob that changes his weapon.

So, yeah, characters shouldn't be able to have Bob's 3rd weapon slot.
