Random rambling...
I had the joy of discussing this with an Amazon customer service rep. Basically, the check was supposed to find books that no longer supposed to be on your Kindle such as returned KU loans and remove them when you hadn't connected to Amazon for an extended period. This does work.
Unfortunately, it also removes any other Amazon ebooks that are "not" supposed to be on your device where Amazon ebook is defined as having EBOK cdetype, valid Amazon ASIN and not present in your Amazon content library. So if you buy a book from Kobo, convert it in calibre and send it to your Kindle, all too often the metadata update will have fetched the ASIN and with calibre defaulting to using EBOK for the cdetype, you are now setup to run into the issue. All you need is airplane mode for an extended period and you can say goodbye to those books.
And thanks for @tomsem for pointing out that the sharing book content via Facebook sets the cdetype to PDOC. I've never used Facebook so never looked at what that setting did.
