Can anyone help? 

I know that the detect duplicates was patched (thank you for patching it) .. Here is the bug record   bug 6713: 4975 | 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.
