Except, of course, that that is incorrect.
It also has to have a different exth 113 (ASIN) record, or else the Content Catalog will get in a snit. e.g. by collections (you can end up with "ghost" books).
Fortunately, calibre conversions will generate an exth 113 field from a UUID, unless you manually set it with Quality Check or something.
Unfortunately, if you send multiple copies of the same book with multiple tweaked titles (so they end up having different filenames and the second one doesn't overwrite the first), they will have the same exth 113 header and that is the primary cause of this issue.
