In BB, it's normal/expected for the notation window to be closed (changed to chord chart) when the Lead Sheet is open. What seems unusual is that if the Piano Roll is the current window, and then you select the Lead Sheet, the Piano Roll window disappears. Seems to me that the Piano Roll should be able to stay rather than be closed. (and if you click on the Piano Roll again after the Lead Sheet is opened, then it reappears).

If Lead Sheet isn't showing up at all, then maybe there was a 2nd monitor turned on previously but no longer present? Maybe return to Options - Return to factory defaults would restore it back to showing up again?
