Unknown Albums shown after sync to iPhone
My iTunes library on both my Mac and my iPad appears complete and correctly identified. The same library on my iPhone, however, doesn't correctly capture the Album information after syncing, instead each song is listed as an Unknown Album from this artist, despite the information being correctly identified by my Mac. Most all of my music has been ripped from CD's that I've bought over the years, so this may be a problem that is specific to music bought outside of the iTunes store. I believe that all my music is correctly tagged music has been tagged as it appears as it should on the Macbook iTunes. I've checked every field and nothing seems amiss on the song info for the tracks for any given album.
I read an earlier post at this site for a "fix" to this that kind of works - When you sync an album onto the phone and you notice that each track shows as a separate Unknown Album, you can delete the tracks from the phone's playlist and then sync it again a second time. Only then will the album will show up on the phone correctly as one, correctly-titled album. That earlier post indicated "this only seems to work when you're adding one album at a time. If you're adding several all at once, this tactic is less effective."
My iPhone 6 is running iOSX 11.2.5, the Mac OS is 10.13.3 and the iTunes version is 12.7.3.46. I'm hoping that someone might be able to identify what I need to alter so that music syncs correctly on the initial attempt.
Mac mini, macOS High Sierra (10.13.3)
