Pizzicato voicing for strings | MuseScore

Ok guys … I am still on 4.2…. and I just decided I want to set my string section to ‘pizzicato’, but no matter how I try … even following the instructions in Add ..Text .. blah blah blah … all I get is an option to adjust Swing settings. Can someone please tell me .. simply and precise;y how I get to set my Violins, Violas and Cellos to ‘Pizzicato’ and then set them back when I am done. Also the mixer no longer seems to show the arco, pizz, tremolo selection for volume control any more .. why? I miss the simple old system.

Help.
