Albums not displaying correctly in iOS Music app when a song uses the "grouping" field
When a song in an album has information in the "Grouping" field, it causes the album to not display correctly in the iOS music app. In these cases, the song in question has its name replaced with the text from the grouping field, and the album's song listing is truncated (not all of them are displayed).
This pertains only to songs that I've added from my personal library, not from songs added through Apple Music. I am using Apple Music and songs/albums are automatically synced when I add them using the Music app on my Mac.
Even if I remove the album and then re-add it to Music, the issue persists. The issue persists even if I remove the text from the grouping field.
The songs in the album are indeed present on my iPhone, because they can be listed in the Songs view. It's only in album view that they are obscured.
Here's a screenshot of what it looks like on my iPhone. It's the same thing on my iPad. This album has 11 songs, and two of them (#5 and #8) have labels in the grouping field ("Fast" and "Medium" respectively). Note the stats at the bottom, where it says the album only has 3 songs (wrong) and is 1 hour 10 minutes (correct).
I believe this is a longstanding bug in the Music app, but I'd like a better resolution than replacing all of my personal connection with the same albums in Apple Music, as this would be tedious and I would lose my meta data.
