"false" duplicates, which are no duplicates in reality

Hi there,

after re-importing my database from iOS to Mac OS via CloudKit after having my Mac OS database irreversibly damaged, I now find a lot of files indicated as “duplicated”, but when I check the duplicates, it is obviously a completely different file, which I don’t like to be deleted.
How is this phenomenon caused and do I solve the problem of these “false duplicates”?

Thank you and regards,

Philipp

damaged how?

And a screen capture of these duplicates would be helpful.
