I can't reproduce this, but my reader upgraded itself to 3.1.1 unexpectedly. I've tried converting the book and sending it over, converting the book and manually copying it, and letting the device driver convert the books during transfer.
Can you upgrade to Kobo firmware 3.1.1 and see if the problem still happens?
