Vendors not selling items they normally sell

So the biggest issue I'm running in to is several traders (LL4) are not selling several things they are supposed to sell. The items aren't unlocked for sale via questing, just loyalty levels. I'm trying to customize a 1911 and none of the parts are sold by the mechanic or peacekeeper like they are supposed to. I've noticed this with a few other guns as well, I just can't remember off of the top of my head. Yes I know I can use flea but I'm doing a playthrough avoiding it until I'm max level. Anyone run in to this before?

EDIT: It also appears to be the applique armors for helmets, certain attachments, etc.
