Importing WAV Files To Rekordbox Issues

Hi,

Since the new Rekordbox release when I now import ripped WAV files from MWP and try and change the Artist, Title, Album, Genre or BPM within Rekordbox the WAV file will become File Not Found.  This never used to happen before and is quite annoying especially with a blank artist field.

I've checked for updates for MWP and there are none so i tested it via Nero and this works fine !!!!.

Has anybody come across this ??
