Which operating system are you using and are you certain that you're not using a case-sensitive file system on your hard drive?
Please post a screenshot of the two rekordbox entries and the file they both point to.
Hi,
Rekordbox creates different entries for one and the same mp3. The only difference is that the file position is in one case with one or more capital letter and in the other case with lower letter - both pointing to the same position on the hard drive (which is obviously not case sensitive). Please fix this issue.
Kind regards,
Peter

Thank you for your reply!
This is the screenshot with the "N" in the file location name of rekordbox:

and this is the one with the "n", both pointing to the same location on the hard drive:

Thanks - that really helps, this could be a weird quirky bug - I'll pass it along to our rekordbox team for investigation.
Can you confirm whether you're using a case-sensitive file system? Open the Disk Utility, select the partition below the drive in question, then press COMMAND+I and get a screencap like this:

Thanks!
Hello,
thank you. The system is not case-sensitive. In line 9 (German) of the screenshot it says case-sensitive - no.

@Peter > Thanks for checking that, I'll pass it along as well. I'll let you know when I hear anything back.
thank you very much!
Hello - wanted to check back about the issue. What is the response of development?
Do you want me to provide additional information?
Kind regards,
Peter
@Peter > Sorry for the delay, I'm waiting to hear back from the rekordbox team.
@Peter > The engineers believe the reason this happened is you are allowing iTunes to manage your files, and after importing the songs to rekordbox, you made a change in iTunes to the artist name (changing the case). This resulted in a change in the folder name, and while the operating system itself doesn't observe case sensitivity, the XML file passed from iTunes for some reason does. rekordbox then identified this as a different file from a different folder, thus creating a duplicate.
Unfortunately the solution is that you will have to manually remove the duplicates.
hmm. thank you for your answer and investigation!
