Music app: Deleted playlist in music showing up in sync window
After updating to macOS 10.15 and migrating from iTunes to Music, playlist folders from a previous music library are showing up in the sync window (under the Music tab) when I sync my iPhone.
I've tried deleting cache files related to the Music app and restarting my computer, but a number of old playlist still show up in the sync window.
Any suggestions how to get rid of them?
