Muse Sounds string articulations do random stuff

Hi!
I've noticed that on solo viola both sul tasto and sul ponticello seem to only work when manually scrolling through the notes with the arrow keys.
When using violin, the flageolett symbol does nothing and flageolett text tunes the sounding notes down a semitone, but weirdly only when using playback, not when using the arrow keys.
Also there seem to be issues when switching back from sul tasto to sul ponticello, there seems to be no ordinario, so once you go sul tasto or ponticello, you can't go back.
I originally wanted the string part on viola but the Muse sounds viola is unfortunately completely unusable for soloistic writic, none of the articulations work as they are supposed to, many notes are swallowed in playback or interpreted incorrectly.
