This sounds more like a support request. Please use the mailing list (https://koha-community.org/support/koha-mailing-lists/) or the Koha IRC chat (https://koha-community.org/get-involved/irc/) for questions like this instead. Please make sure all your items have homebranch, holdingbranch and itemtype set. These fields are mandatory for Koha to work correctly.
