Registration complete shoing in primary menu

Hi - I installed the plugin without difficulty but the notification PAGES the plugin uses to show registration completion etc are showing in the primary menu (see website http://www.bebodysmart.co.uk) under memberships.
I have tried switching off the various Protected Content plugin pages using the green toggles in the Protected Content | Settings menu, but this has no effect. See Screenshot
my direct email is sales@calcouk.com
Can you help please?
Warmest regards Ron
