Hi there,

The theme has two different menus, one for the mobile site and one for the desktop.

To create a menu showing sub pages for the mobile, you’ll need to go into the wp-admin, appearance>menus and setup a new menu with all the pages you’d like displayed on the mobile site in the correct order as main pages (as this menu only shows them all in a list). Then save the menu, scroll down and tick the checkbox for the mobile menu navigation, so that this new menu (including the subpages will be shown). http://screencast.com/t/6mI7rkRg
