[Koha] Still unable to get "detect duplicates" to work

Can anyone help? I know that the detect duplicates was patched (thank you for patching it) .. Here is the bug record bug 6713<http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=6713>: 4975<http://bugs.koha-community.org/bugzilla3/attachment.cgi?id=4975&action=edit> | 5791 I still cannot get it to detect duplicates .. when I import, it says "0 records with at least one match" I updated the bug report on October 7 with records and also sent in more records today. Does anyone have any ideas how to fix? I have the latest version of Koha and patches. David
