Calibre version 1.32 (64bit), Kobo Glo 3.2.0, and win7, all epubs only..
I have a multiple library setup, which generally works well. (Thank you for this option as it has helped organise my life...

) However there are some strange things happening when I quick change, or move/delete, on an irregular basis.
1. When selecting and transferring files to the Kobos, I sometimes use the "quick switch" library function moving multiple books from "fantasy" library, then changing to "sci-fi" library hoping to move multiples from there. However, only one book at a time will
then transfer to the Kobos. If I try for another book, or use multiples, the first book will disappear, and be swapped for the next... Happens with both Kobo Glos.
Also:
2. When moving a book from the original library to another e.g. When I have read a book I transfer it to a "Read" library and delete the original, sometimes the book (.epub) disappears, or the cover, in the second library. I now have to go back and check each transfer.
Is it a Kobo issue, or a library issue? Please
