Hi,
I have 1434 books in my Calibre library and 1435 (1434 + the H2O manual) on my H2O (622 on the device and 813 on the card), which is as I expect.
All the books in my library show up as either on the device or on card A (and not on both).
However, when I run KoboUtilities (having selected all the books in my library

), it tells me that 2 books aren't on the device:
(Ignore the fact that this was a rerun! It did update loads of books the first time I ran it.)
Any ideas why this might be happening, and how I can identify the two books in question? Or should I just not worry about it?
