Rekordbox Export

I apologize if I am repeating a topic already discussed. I'm just having a hard time finding anything.  I am trying to export a few playlists for a gig. Once the export is complete I get an error/export log in which most files state as follows:"The file is in the format that CDJ/XDJ/mobile device doesn't support."  a lot of these tracks I've used and played on many occasions. And most if not all have been purchased from Beatport and some from Traxsource. I am currently using an RX3 and hadn't had any issues until this point. I've attached the report for your review. Any suggestions would be greatly appreciated.
