Track Information Disappears in Collection List


I just got Vox and am using the latest Mac OS version (3.5.1). I have created a synced collection.

When I add a track to the collection, everything looks fine initially. Then when I add subsequent tracks, the information (track name, etc.) disappears on some of the tracks that I had added previously. The tracks that have lost their information, no longer play, and no longer sync with my iPhone.

I just added a track, and 30/40 tracks info has disappeared and the tracks no longer play.

This flaw is rendering the application unusable for me, since creating my own collections in VOX is exactly what I purchased the app to do. Help!
