iTunes Match Frustration

After several years of syncing my music library to my iPhone via a USB hookup, I finally subscribed to iTunes Match the other day.  For the most part everything went well, but three or four of my playlists are empty on my iPhone.  I understand that a playlist won't upload to iCloud if one or more songs in it are problematic, but I've tried all the solutions written up in the past, to no avail.  I tried to create a duplicate of one of the playlists but it too didn't sync its contents to the phone.  Any thoughts would be appreciated.  

On a related note, I would like some help understanding the various iCloud status terms in the Music app on my computer.  I understand "matched" and "error," but I'm seeing the terms "duplicate" and "ineligible" as well.  Are these latter terms problematic to iCloud syncing?
