Learning Dorico: Piano Roll not showing in PLAY mode

I’m switching from Sibelius and learning Dorico Pro 2.

I’ve been watching the tutorial videos but when I go “Play Mode” I have no piano roll visible and the “flows” at the bottom seem to have some sort of issue. Is there a bug in my download (do I need to reinstall)? Or am I missing something? This is what I see (https://drive.google.com/open?id=1SnTGOQK8Inn_uU1dd2Ts_32TyulRrO_l). As far as I know I haven’t changed anything, just tried to look around for the piano roll.
