My order / units have reached the Amazon Warehouse on 2nd dec and have also been split into various warehouses by Amazon but my listing status still show's "Out of stock Replenish inventory" and on top on the Manage Inventory Page under "Search and Suppressed and Inactive Listings" tab in "Fix Your Product" column it is showing "Inactive Lisiting (1) Out of Stock (1)"

How should I fix this why is it showing "Out of stock Replenish inventory" when my units have reached and have been splitted as well

how can my listing go live/active and be available to sell?

and also when i click on "Out of stock Replenish inventory" which is under the "Listing Status" column it takes me to a different page where it says "Merchant SKU already exists. Merchant SKUs cannot be reused, even if a previous offer using the SKU has been deleted. Please use a new SKU to create this offer."
