This happens only if deletion and addition happens together; if you disconnect and add, the collections show correct values.

I ended up comparing every collection in kobo with calibre and deleting (in kobo) whatever showed difference. Logging out of kobo might have been easier, I believe. Also, restarting doesn't seem to fix it.
That doesn't sound right. If you delete a book using calibre, then the driver will remove the collection entries for it. And if you add a book, it should add the collections entries. If you resend a book, and it ends up with a different file name, you will have two books. Calibre will see them as two copies of the same book, but the device will have two books. There should be collection entries for both books. And if you delete a book and then add it in the same session, all the entries for the book should be removed and then added.

And, if the collections don't end up correct after all the adds and deletes in a session, unplug the device, let it do its work and then connect again. The collection management will be done at this point for the books on the device that are in the calibre library. That should fix any inconsistencies from the above.
