Mysterious Disappearing Inventory: How Did My Shipment Count Drop from 944 to 776?

I sent a shipment with 944 items. While the shipment was in “Receiving” status, all 944 items were counted. Then, once the shipment was closed, the count dropped to 909. The next day, when I opened a research ticket, it had decreased further to 857. While I was uploading invoices for the case, the count went down again to 818. After a few days, I checked once more, and it had dropped to 776.

Here’s the count progression: 944 → 909 → 857 → 818 → 776

How is this even possible? How do they initially scan all the products and then keep “losing” them? Is this just a system issue? I recall having a similar issue with another shipment that was eventually resolved, but this time, the discrepancy between the expected and scanned product count is significantly larger.

Thanks.
