Auto relocate files issues (Help pls :-()

Hi all,

At the start of the new year I moved my Rekordbox files to an external harddrive to create some space on my mac. I still use the same Database to ensure I have the same playlists, tags, etc. I also have a Timemachine backup of my old mac on this drive. 

However, I can't get my Rekordbox to auto relocate the files from my library. I'm 100% sure they are there because when I do it manually I find the tracks. When I try to find these tracks through finder I can't find them either.

How do I fix this? I have checked the permissions via 'get info' of the entire drive and my privilege is both "read & write"
