I'm a brand owner of the listed product. I was the one who created a listing. Product was selling as FBM and I wanted to send some to FBA and went to add product - search ASIN - sell one - entered a price - accidentally entered the same SKU as FBM listing had and submitted. New listing was not created, but the existing FBM was converted to FBA and all listing descriptions were gone. Listing has search suppression "no item description". When I go to EDIT, I'm now NOT a listing owner anymore and I don't have "product details" and "safety and compliance" tabs, I can change price only. There is a button "Suggest changes to product information" and all tabs show up. How to restore listing ownership???
