Bug report: 3 Concussive X guns name bug

Hello, I already own a 3 concussive X  unlocked in my collection, those are

1. Soned con X

2. Revenant con X

3. n7 piranha con X

but in multiplayer loadout, they show the name "Concussive I"

Hope this bug will fix soon, thanks in advance :]

Best Regards
