So apparently, even though a shipment has been closed, that doesn't mean the discrepancies' don't keep changing.

So can someone please explain how the "units located" quantity continues to change (plus or minus units) days, weeks, and even months after Amazon closed the shipment?

How do you keep track of all of these changes that we weren't aware of until we found a shipment that had these changes and then we went through the entire years shipments and we found multiple shipments with this type of change (units located).
