I've been having this really frustrating problem for a long time. I select a sort/group preset(say Artist/Date/Album) and when I refresh the playlist (either with playlist bind or adding a new folder) the sorting disappears and tracks are displayed in the same order as they're found. I'm using panelsui 0.13.8 beta. Am I missing something?

try making a new preset and save the preset to your liking. then it should work (worked for me)
