Grey Circle on iTunes "iPhone" and "iPod" and duplicate entries
Okay, I've seen a few topics on this but I haven't found a solution yet.
On iTunes (12.7.3.26) I have quite an extensive library of both purchased on iTunes music and older CDs that have been ripped plus a very small amount of songs from Apple Music (current trial). This problem persists across the entire library. I'll focusing on one recent playlist with only 41 Songs (3 Apple Music AAC audio file, and 38 Purchased AAC audio file). On iTunes on my Mac these 41 songs appear and play as expected.
On my iPhone X (iOS 11.2.6 with 188 GB Free) while connected to iTunes I see only the Purchased AAC audio files but the song count is 170 songs. Some are duplicated (with the grey dotted circle) while some are correctly copied over. While some are not copied over and have the grey circle. All of the displayed songs are Purchased AAC audio files. None of the Apple Music files display. So 38 purchased songs replicate to 170 - some duplicate, some not.
However, when I look on the iPhone when not connected to iTunes I'm only seeing 15 songs. Both Purchased AAC audio files and Apple Music AAC audio files. More than half of the songs are missing.
I have an iPod touch that I use in my car and it has the same strange behavior as my iPhone.
I read a post that suggested to manually delete the grey dot songs from iTunes for the iPhone library but that's not working.
