Checked the data to see if what UPC has a duplicate when checked, there are no UPC that has a duplicate, checked with sir Rey to see on his side if there are duplicates and if they can be deleted, as per sir Rey, it can be. He deleted the duplicate UPC and sent me the list of UPCs with duplicates. Sent it to sir Jowel and advised that it is now deleted. He checked the update on his side, and as per checking, it is now OK.
