The latest Mac operating system (macOS Sierra 10.12) is not supported by Print Music 2011. Finale v25 is the only product that is currently updated for macOS Sierra.
In the full version of Finale, there's a lot more to this dialog screen. Does Ctrl+K open up a different screen? If not, try right clicking some of the blank white space on this screen
On Finale v25 to do this I would use the Score Manager (Command+K or Window>Score Manager)
