That would be because none of the Angels have used thier key on the back door to the place since reset, swoop. Chests are tied to opening the place up. If your other characters can see the chests, I have no clue.
Find the locked door (over on the side) and knock. This will refurnish the Angels, and any other place. The Buckle is tricky. The proper locked door is inside, straight back from the front door.
