You don't say which version of Koha you are using, but do you by any chance
have duplicate Control Numbers (Marc 001)? You can verify this by running a
SELECT GROUP_CONCAT(biblionumber SEPARATOR ', ') AS biblionumbers,
EXTRACTVALUE(marcxml,'//controlfield[@tag="001"]') AS id FROM biblioitems
GROUP BY id HAVING count(id) > 1;
