How to delete empty itunes playlists from Roon?

I have recently migrated my core using a back-up file. I have also copied over the full library. However I have not used (and do not want to use) iTunes on the new Mac Mini.
This has resulted in quite a few old iTunes playlists showing in Roon as empty. When I click on the … to edit these playlists there is no option to delete them.

Is there any way to remove these ‘empty’ playlists without having to use iTunes?
Is my only option to reset the core and start afresh with a clean scan of my library?
