Need a genius to answer: How does one locate files of phantom playlists from itunes, that aren't visible in itunes (because they were deleted long ago), but only become visible in DJ music apps (e.g. Recordbox & Traktor) which pull data from itunes?

Hi Apple community! I'm hoping there's a genius among you who can help solve a problem that has eluded many knowledgeable people, including Apple Support Supervisors.

For starters, I have a MacBook Pro running with Sonoma 14.6.1. I have itunes Match, not a subscription to Apple Music. These phantom itunes playlists were created years ago, before itunes became Apple Music, & then they were deleted last year (in 2023) when I reorganized my playlists. All of my current playlists have multiple songs inside them, but these phantom itunes playlists are empty, with no songs inside of them, so essentially they're just playlist titles, like named empty folders.

Initially I had 3 phantom itunes playlists. Upon a suggestion from Recordbox, I was instructed to look in other Apple apps, such as Apple TV, Books, & Podcasts, & to my surprise, one of these phantom playlists was found in my Apple TV app under playlists, where it could be easily deleted, & then no longer visible in my DJ apps. Unfortunately, after searching all the rest of my apps, the other 2 phantom playlists cannot be found.

Since separate DJ apps continue to show these 2 phantom itunes playlists, it means that these phantom playlists exist somewhere within my Apple software or device. If you can please help me locate them so I can delete them as they are a nuisance, then you're a genius!
