After some tests, looks plausible that the sorting key I couldn't determine is book title.
Also, deleting a file from ONLY the device, when showing the books from ONLY the device (on device memory, I mean, using the button showing a Kindle), doesn't select any other book. Maybe the problem is related to this :?
Again, thanks, and if you want me to carry more tests, just ask.
