I obviously don't understand how the synchronization works. I'd like to correct book metadata on my ancient Kobo Glo. Here is what I do:

- I edit the metadata in the Calibre library
- I mark all books and click 'send to device'

The result is now that for many books, the library table says (2 books) - or even (3 books). WTF? I'd have expected that the metadata on the device are updated when I modify them in the library. Instead, a new entry is added and the chaos that I wanted to clear up gets worse.

I'm sure this is due to the fact that I don't understand something. Is there an automatized way to drop double entries from the device, keeping just the newest version?
