Classical App Playlist Issues

I have some playlist issues with the Apple Classical app. Not sure if I’m doing something wrong. I’m using my existing Apple Music playlists, so I don’t know whether these issues apply to new playlists created in Apple Classical.

Adding to a playlist

1) If I want to add a track to a playlist, it does not warn me if the track is already there. It adds it, and will continue to do so multiple times. On the Music app, I get a message that the item is in the playlist, and I have the option to add or skip.

2) Furthermore, when I add to a playlist, the playlists display in some random sequence I can’t identify.

3) Finally on adding tracks, there’s no default to the last playlist I added to, as in the Music app. So I have to scroll through my playlists, which are in random order, each time I add a track.

Viewing playlists via the Library

The playlist access via the library’s is weird. It shows a few playlists, but then I have to select each time to view all.

When list displays, it’s in recently added sequence. I can click the menu on the top right to switch to alphabetical, which is my preference, but the app does not remember my choice and I have to reset it each time.
