iOS 18 Groupings no longer show in Music app

For the past few versions of iOS, tracks with Groupings data would show up in the album track view in the Music app.

This has been helpful with my library of music with hundreds of albums of classical music where groupings are where the overall work of a multi-part piece would show.

A while back, Apple also added the Work/Movement metadata, a newer option to view these.

This latter option still works in iOS 18, but suddenly Groupings no longer show. As my library is literally thousands of tracks using Groupings as the work name, I do not have the time to manually adjust this for every track to the Work/Movement option.

I want Groupings to show like it used to.
