Hi Peter,
Wanted to report this odd bug I just encountered.
I just updated my 2023 M2 laptop's version of ST3 from the Apple App store to the new 3.7 release. Interestingly, once the update was done I launched the app and found that the song order in my playlists were scrambled - meaning that they were then in new, random sequences.
I restored from my last backup and the set lists were accurately restored.
