Sudden Change in NotePerformer Swing Articulation Playback

I’m working on a chart for jazz ensemble. Very suddenly today the way NotePerformer (4) plays back articulations changed, separating notes too much. Anyone in the collective wisdom ever encounter this and come up with a fix?

Summary

I have a playback copy in a separate flow, where I use lots of slurs, articulation marks, and audio-only tweaks in the piano roll to coax the best approximation of swung jazz feel I can out of NotePerformer. I was getting half-decent “da-du-da-du-dot-dah,” etc., playback until just a little while ago. I’ve tried reapplying a swing tempo flag, but it didn’t help.
