Spotify only partially syncs my playlists

[acarlrpi12]

I am trying to sync my offline playlists to my Moto X 2nd generation phone. I added some new tracks today and it only downloaded one of them. So I followed the instructions for clearing all of Spotify's data off my phone to perform a clean install. After that, when I tried to sync the playlist again even fewer tracks had been synced than before. I then found a comment from a while ago saying that I should try moving the music to another playlist, but when I did that 2 less songs synced properly.

I made sure that I am not at the 3333 song limit, I only have a little over 200 songs. Additionally, my phone has almost 20 GB of free space. I also noticed that all of the albums that are failing to sync have their album title and artist greyed out on my computer.

Are these tracks unable to sync on Spotify cloud or local added files on your PC etc?
