Q: I received a product not listable warning? What can I do?
A: The "product not listable" warning is not an error message. Error messages state "Error" and they prevent items from posting. "Warnings" are more like notices or just messages from eBay. Product not listable is just a message from eBay letting you know that they have attempted to match the item with one from their eBay product catalog, but could not find an exact match, so they have aborted that process. But it doesn't stop items from actually posting to eBay, it just means that it won't be attached to one of their PBSE (Product Based Shopping Experience) Pages. So there's nothing to fix for this. You'll likely continue to see it if eBay can't determine an exact match while listing.
