This issue talks about the the report 'Releases which have multiple ASINs' which can be found here: https://musicbrainz.org/report/MultipleASINs. It also lists releases with multiple ASINs, which are identical, but point out to a different localization of the Amazon website. You can see an example release here: https://musicbrainz.org/release/32e2ac34-0a31-4e5d-b731-7afe2199d728. There is no guideline which prevents users from adding same ASINs (with different localization) to the same release, so the report should not consider the links as dupes in this case. Some interesting talking points for this can be found in https://musicbrainz.org/edit/42285691. Alternatively, this ticket can be re-purposed and the documentation changed if you consider adding multiple same localized ASINs unwanted.
