DT will not sync the correct number of songs on each playlist

Hey!

So I run DT on my Windows 10 computer and AirSync it to my Google Pixel XL2 android phone.

But lately all my songs do not show up.  The songs are there on the phone, but inside the playlist they are not.

Ex - iTunes shows/has 60 songs in Playlist 'Ozzy rules', but after I AirSync, 'Ozzy rules' on my phone only has 7 songs.  AirSync returns 1 error.  When I look at the log file, it says 

{Updating Device playlist 'Ozzy rules' with 7 items.  60 media sync records present}

I've reset the library several times, no luck.  I've deleted the files in the 'DoubleTwist' folder on my phone and re-synched, no luck.

Any why does DT create playlists that says 'Recently added' ?  Because my iTunes library has 7500 songs, but my playlists only have 1700.  I don't want 7500 songs on my phone memory, only my playlist ones....

Here's what the error says:
