Bangalore Smoke Grenade Bugged!

Bangalore's smoke grenade isn't doing any damage for some reason.  I have a challenge to hit enemies with her smoke grenade, and can't finish her spotlight pass without it.  I've tried shooting people directly with the tactical, and even aiming it to the side a bit to hit them with one of the three smoke bombs that come out.  Nothing works.  Went to the firing range to make sure I wasn't just trash, and it didn't work on dummies either.  Clip attached below.  Please fix asap!
