Units Marked "Defective" in FBA Shipment

Hi everyone,

I’m dealing with an issue where it seems pretty much all units from my recent FBA shipment were marked as "defective" and put in unfulfillable status. I’ve been working with this supplier for a while with no problems, so I’m surprised by this.

I’ve asked my supplier to confirm everything was packaged properly, but I’m also wondering if Amazon may have made an error. Has anyone had their products incorrectly marked as defective? Any tips on how to resolve this quickly? I asked amazon and they said I have to wait another 10 days until I can ask them to investigate this shipment but the shipment is in 'closed' status so not sure what is going to change between now and then. I want this issue sorted asap so i do not run out of stock
