GS1 BARCODES BEING REJECTED WITH 8572 ERRORS

HI . so i recently purchased some gs1 codes so as to list new products .

however, when i do this , i get the error 8572 or one of the others such as

(5461, 5665, 8572, 8541)..ihave emailed amazon and they have said

to activate your gs1 , you need to list the product using those barcodes . incase , if you face any issue contact us with the screenshot ..I have done this and used a blank listing but still get the same error ..

really annoying and iam stuck as to how to resolve this. Amazons replys are not very helpful
