we got multiple listings in all the EU marketplaces with the same issue

there is a matching error 8541 on the item_name value

and it makes no sense for two reasons:

1. this is the error message that I receive upon opening the Edit page for any listing or trying to update via upload, the message itself as follows: "The value 'ABC' specified cannot be used as it conflicts with the value 'ABC' for ASIN Z in the Amazon catalogue. If this is ASIN 'Z', update the value to match the ASIN data. If this is a different product, update identifying information (UPC/EAN/Part Number/etc)."

value 'ABC' specified here 100% identical to value 'ABC' for ASIN Z in the Amazon catalogue, so I do not get it how there is a conflict if this error message returns two exactly the same values for a proposed one and for the one in the Amazon catalog.

2. the error message always contains item_name values that belong to a different marketplace, such as, if I work on a listing in DE marketplace, the error message will contain values in Italian, not in German as one would expect.

countless case with the SS team got us no resolution, it's always the same , they keep replying that to solve this issue we must update this ASINs data with the value that is set for this ASIN in the Amazon catalogue, but that's impossible for these two reasons explained above. on some random cases we were able to get support team to perform a backend update , not sure if they actually updated anything since nothing changed and the problem still shows on the edit page.

I see loads of articles here regarding 8541 error, but did anyone had it with such circumstances ? any suggestions on how to solve it?
