Missing shipment quantities in report type _GET_FBA_MYI_ALL_INVENTORY_DATA_


for some shipments the shipment-quantities are missing in the report type GET_FBA_MYI_ALL_INVENTORY_DATA
This mainly happens for shipments with status “READY_TO_SHIP” in NA. But also in panEU. The quantity is missing in the field “afnInboundWorkingQuantity”.
There are not many affected but for example the quantities of some SKUs from the shipment “FBA16TXL3VSN” are included in the quantity of the report and others are not.
And there is no reason for this different handling,
Could we have a small bug here?
