NPC animations not cooperating with UGC items

I’ve been using UGC items for my NPCs. I have several UGC items, be it hats, shoulder armor, cloaks, belts, everything, from headgear to waist to back to shoulders. However, when I play an idle animation on the NPC, all the UGC items act as if they are connected to the head. How do I fix this?

NOTE: I’m using the insert asset plugin where you enter the item ID and it loads it in the game. It consistently has problems with UGC items, and every time I have to manually alter attachment positions so it’s in the right spot.
