Rather than explain the apparent inconsistency, may I say what has just happened ?
I found the 2 Amazon Kindle books in my Downloads folder. I added them to my Calibre library. I checked to see that both had AZW-extensions. I uploaded both to my Kindle. I then checked that they had been uploaded. In the right-hand pane of Calibre, I opened each book in the Kindle library, and found that I could read it. I ejected the Kindle, found the book, and tried to read it. No luck -- "Unable to open item" again.
