[Koha] why do i get a Duplicate Record suspected message while adding records while there is no similariyty between the books in content or name or author or copy number

Hi I get a Duplicate Record suspected message while adding records while there is no similarity between the books in content or name or author or copy number or DDC no or keywords,or publisher or keywords. When i was adding the record for Dermatology and sexually transmitted Diseases book I get the message Is this a duplicate of Adolescent medicine today? How does this show up?Any idea anyone. I know that i may be able to skip this by clicking the button >No, Save as New Record But i want to know why Koha shows this message -- View this message in context: http://koha.1045719.n5.nabble.com/why-do-i-get-a-Duplicate-Record-suspected-...
