My ASIN has been removed and is listed as inactive (out of stock) after some already being available for sale

I’m a brand new seller and have just shipped (100) of my first product to Amazon for FBA. For the past week I’ve seen that more of the unit are being set from reserved to available and I could see that my product was listed and available to purchase. Today I saw that available products are now categorized as stranded inventory for the reason of “listing error”. I did some research and I think its possible that it could have been flagged for a duplicate product. The thing is my product is not a duplicate, its has its own original design, photos, description, UPC, etc. I get that some other products are similar to mine and maybe another seller has flagged it as a duplicate, but my main question is how do I proceed going forward. I have put in a support ticket which Amazon says they will get back to me within 3 days. When I search similar products to mine I see a bunch that are the EXACT same product with small differences in how they show their photos and descriptions. They all have unique ASIN’s. Wondering why mine was removed.

Any insight would be greatly appreciated.
