Please note that Amazon Policy does not allow duplicate listing in Seller Central, which are two SKUs under the same ASIN with the same fulfillment type and the same product condition (both new or used).  

There are three scenarios that Amazon considers acceptable for two different SKUs under the same ASIN. 

1) Two different SKUs under the same ASIN have different fulfillment types but the same product condition.

2) Two different SKUs under the same ASIN have the same fulfillment types but different product conditions.

3) Two different SKUs under the same ASIN have different fulfillment types and different product conditions.

 BQool will display them all on the manage listings and reprice them properly. 

If the seller encounters the Duplicate listings situation, please delete one of the listings in Amazon Seller Central, and no other actions are needed.
