The problem is not in CC but in calibre, and has been there since December. I have a fix and am testing it.

You can work around the problem by:
  1. Deleting all books off the device. What you did (file manager delete followed by find missing books) is a very efficient way of doing that.
  2. Make sure calibre is not running.
  3. Delete the calibre metadata cache files. They should be in c:\users\your-user-name\AppData\Local\calibre-cache, named wireless_device_long-string-of-nonsense. Delete all of them
  4. Connect CC to calibre
  5. Send the books. Perhaps test with a few to be sure that something else isn't going on.
Thanks for your patience!
Since I have all my books in CC now I didn't want to delete again. So I

1. deleted Calibre cache files after closing Calibre.
2. deleted a book from my device using CC.
3. started Calibre
4. connected to Calibre wirelessly - all metadata was set to Calibre again
5. sent the book again
6. profit!

All went well. After I deleted all my books last night, it seemed that sending 20 books thru the wireless connection took a while. I sent them by connecting by usb instead and it was a lot quicker. When I connected wirelessly after that, CC did need to send the metadata again of course, but overall it seemed much quicker. Is it my imagination or is usb a lot quicker? I keep about 800 books on my tablet.
