Beat Buddy Manager only retains 12 of the 15 songs in folder

Every time I create a new folder and build my set list of 15 songs, I save it and then sync it with the SD card. When I load the SD card into BB, all 15 songs are there. I then close out BB Manager and when I reopen it, the last 3 songs of my 15 song set are no longer there! Ideas?

Please take out all apostrophes, commas, and periods from song titles. Do they still disappear?

Problem solved! Thanks!
