Flagged my inventory as unfulfillable defective

I recently launched a magnesium supplement on Amazon and sent in 500 units.

About 80 sales in, Amazon flagged 334 units as unfufillable->defective and asked for me to remove the inventory.

I contacted support, and they stated it was due to expiry dates, which they then checked, took photos and saw that it was in fact fine 08-2024. Support stated they’d set the status of the products to Available.

But this did not happen, so I enquired again, and received another response that: “food supplement that does not contain ingredient information in the ingredients field” but this is not true either as the ingredients are clearly stated on the product page in the correct field.

They then flagged another 69 units as unfulfillable->defective.

I now have to remove all these units, but the expiry dates on them are fine. They sent me photos from the warehouse with the correct dates on the bottle.

Has anyone been through a similar experience?
