New UPC attached to the existing listing

Hi all,

I tried to list a new product on Amazon with new different UPC, however I always receive this message:

The value ‘Generic’ specified cannot be used as it conflicts with the value ‘INFYNITY’ for ASIN Z in the Amazon catalogue. If this is ASIN ‘B08NTRTZ5G’, update the value to match the ASIN data. If this is a different product, update identifying information (UPC/EAN/Part Number/etc).

My product is rubbish bin not iWatch. I do not have brand name, so I marked it as no brand name, but this error keeps showing.

Anyone has an idea how to solve it?
