Stranded Inventory - Listing Error

My Amazon Canada FBA inventory has become stranded due to a listing error. I reached out to Seller Support for assistance, but they were unhelpful. Their advice was to delete the listing, wait 24 hours, then recreate it using the same SKU, and wait an additional 48 hours. I followed their instructions, but the issue remains unresolved. Now, three of my listings are affected and showing as stranded inventory.
