Left Hand Pizz Sound on strings, using NotePerformer carries the sound to other notes

So, I am using Note Performer, and one of my pieces, involves a switch from left hand pizzacato, and then regular bowing techniques. However, if I assign the “+” marking, every note after that will be played in Pizzicato, when I only want the note it is assigned to, to play pizzacato. What must I do to stop it from keeping on playing pizzicato?

Add a “nat” playing technique and hide it. It’ll cancel out the pizz.

Well, this should work as expected, as the LH Pizzicato technique is defined as Attribute in Dorico (And it does work correctly here…). Are you sure you have chosen the correct PT?
