Marketplace Stock Not Depleting

[Waikeeki]

I created a listing with 3 no copy gacha items as the stock. Two of them have been sold, but for some reason it is still showing 3 stock instead of 1. Under transactions it says "delivered" for the both of them, and indicates an item being transferred from the store. All other listings seem to be working fine and reducing in stock whenever they are sold, except for this one. Is this some kind of known glitch? How can it be fixed?

Turns out it was indeed a bug. After the last item was sold, the stock immediately went from 3 to 0, and the listing automatically switched to inactive as usual. Not sure how often this happens, but I guess if you have the same problem, then just wait until it sells all the stock and it should be fine. The only issue is keeping track of your inventory will potentially be confusing.
