Basically the Organiser replaces the Navigator so you don't need to have both open at the same time.
Close the Navigator and you can select the layouts in the Organiser and you will have the option to print them.
If you do keep both Navigator and Organiser open then either don't have the Organiser showing the layouts or don't have any layouts selected in the Navigator.
It seems to get confused when you have the layouts active and selected in both.
