Grace notes playing as arco instead of pizz on contrabass (Playback issue)

1) Make a new score

2) On the "add instruments tab", add contrass (double bass violin)

3) Add two crotchets (one after the other)

4) Add a grace note before the second crotchet

5) Press play

(*On a technicality there is a slight workaround to this (as shown in the example composition) but it is very impractical)
