Can't get rid of guitar scoops in playback

I’m writing for a funk band that includes electric guitar, which I have not written for very much in Dorico, and everything was working fine for a while, and then all of a sudden without warning the guitar playback started putting scoops on every note, both when playing back written material and when playing from the MIDI keyboard. I can’t figure out how to get rid of it; I’ve checked the playing techniques lane and there’s nothing weird there, I’ve tried changing the guitar sound and the expression map, I even created a new guitar part and copy/pasted everything into it and it had the same problem. I’ve attached a small example of the project.

You are using the expression map for HSSE Nylon Guitar with the wrong instrument. That expression map sends keyswitch C0 for the natural technique. But on the Clean Strat Guitar that will trigger semi-slide up.

Either set the expression map to default, or write your own map for the techniques of the clean strat guitar.
