Hanging notes in 6.1

Dorico 6.1, note performer 4, mouse input. Now at random hanging notes appearing on playback (the recordings are fine). What may be causing this and how to fix it? Never happened before!

Do you have trills (or similar passages) in your music?

Is your problem the same as this thread?

No trills anywhere in this score

Cyfarchion cynnes, eine gute Zeit, mat beschte Gréiss, with best wishes
