MFN Listing in Stock, but on Amazon “Unavailable”

I’m trying to sell units of an existing ASIN here on Amazon Poland. I entered over 28 units in stock, waited 5 days, no errors on the listing, and the listing is still showing as “currently unavailable”… even though the listing is “Active”.

The original listing is selling the product on Amazon Germany.

It’s odd though because at the bottom section “Manage offers in other marketplaces”, my “28” quantity seems to show up for Amazon Europe but not for Amazon Poland. (screenshot)

Anyone know how to get it to be shown as “available” for retail buyers on Amazon? I have the same exact issue for 30+ products.
