Cannot delete items generated in Paper UI. Deleted also in jsondb

I have a bunch of Kodi items that I would like to delete, but when deleting it says Error 404 - Not found.

I googled around and someone suggested to delete in teh jsondb files.

Stopped Openhab
I used grep -R in the folder and started to delete until there was nothinh related to Kodi left.
Also deleted all the files in backup directory.

Tried starting Openhab and they are still there. Even tried rebooting the server with out any differance.

I am now out of options. Hope someone can help me out here.
