A Phantom tag waveform, without sound, at the end of a few tracks

 I've never had this problem before and it only occurred on a few songs but some of my tracks have the waveform modified, they are fine in Rekordbox or playing them on my computer but when I play them on my XDJ-RX there's a waveform tag-on at the end of the actual song / waveform with no sound.  I see an additional 20 seconds of waveform, and 20 seconds of time remaining, but there's no sound, so I think I have 20 seconds left to play or mix out, and the song just ends.  The total time listed in Info on the XDJ-RX matches the total time listed in Rekordbox, but when you play it the waveform is definitely modified with the added tag on.  I deleted those directories from my USB, verified they were deleted, then added the directories back onto the USB, same problem!  I've only ran across five songs like that so far but I don't want to be DJing a gig and run out of song because my waveforms have phantom tags at the end.  I ensured both my Rekordbox and XDJ-RX had the most recent software upgrades.  I bought a new USB, FAT32 formatted it, dumped all the directories onto that new USB, same problem.  I then went through every single song in the six or seven directories, verifying the end of each song was actually there, and only found the same five songs that were defective, which was a relief.  I'm going to run those songs through ACID Pro, Beat Map them, change the tempo very slightly and then render them as a new MP3 file, hopefully that'll work.  Anybody seen this before?  Any advice????
