Product Stuck as ‘Currently Unavailable’ Even After Moving to Seller Flex | Variation Issue | Need Urgent Help | Please look into my post

I’m facing an issue with one of my product.
We sell Gym Dumbbells with the following weight variations:

• 5 kg pair
• 7.5 kg pair
• 10 kg pair
• 12.5 kg pair
• 15 kg pair
• 17.5 kg pair

The issue is specifically with the 15 kg pair variation.

Problems is:

1. The product is not going live.
2. It shows as “Currently unavailable.”
3. There are two SKUs listed under the same ASIN when viewed in Manage Inventory.

I tried moving this product to FBA (Seller Flex), but during inbound, I receive this error:

I already contacted Seller Support, but the issue remains unresolved.

I want to make this product live again.
Would it help if I remove this variation and recreate a new one under the main ASIN?
