Bittorrent Sync not syncing everything

Hello everyone!

I just started using Bittorrent sync as a solution to sync my music from my computer to my phone. My music library is a little over 1500 files and 13.1GB. It will say it is done syncing and there are still about 80 or 90 songs that didn't sync. Is there a fix for this or is this just the result of it being beta? My phone is an LG G2 if that matters. Thanks!

The way I have the file names set up they all read "Artist Name-Song" so their all along the same lines as "Foo Fighters - My Hero" (minus the quotes)
