MuseScore Strings - Pizzicato Tremolo is not pizz.

Using the MuseScore Strings soundfont, if you notate "pizz." the playing style will change to pizzicato. If you add tremolo lines on the pizzicato, it will switch back to arco even if you don't notate it. I wanted to use this for ease of 16th note runs, but was confused to hear it switch back to arco. I've attached a file to demonstrate the glitch.
