[AsterixKobo]

Hello,

I have all my books on calibre correctly tagged (mostly by centuries of the fiction)

I use custom column to handle the shelves on the KOBO (as describe on this forum )

I just noticed that on the kobo device it s a big mess.... some books appear on some collection where they should not be. Collection are missing... I do not have any backup in order to restore the db file. I did not changed the version of the firmware neither change calibre version. I just transfer some books from time to time.

OK now the mess is done but how to repair it: What is the best way to put back correctly all my shelves in a good order ? Do I have to transfer all books from calibre again or is there any more simple solution ?

Many thanks for the advice

Cheers
