Rekordbox Cloud Library Sync - USB sync issue

Hi,

So I recently upgraded to the Creative Plan and in the process relocated my library to my connected Dropbox account. I uploaded tracks to the cloud and then deleted originals in the process as it appeared that Rekordbox located them in the Dropbox storage anyway and they would play without issue. However, I've come to a bit of a hit a bit of a sticking point when it comes to updating my USBs. 

So for the files that were 'copied' to the drive as opposed to 'moved' to the drive, it appears that when I attempt to update by USBs Rekordbox looks in the original location and then wont add it to my USB stating 'file not found'. A workaround is if I've manually loaded each track into the Rekordbox player it appears to then use the Dropbox file location and will add it to a USB stick. Only issue is that it resets every time I close/reopen Rekordbox so it's only really a short-term fix so i can get some tracks on there.

So my questions is what to do in this situation? Is there any way to maybe consolidate my library so that Rekordbox stops looking in the original file location and goes only to Dropbox? (I do still have all of the original files and can put them back in the location if necessary)
