Hello Stefan McRae
The right side menu items are not loaded in the mobile. Please check Template Options -> Naviagation -> Off-canvas -> Select Off-canvas Menu. Here Main Menu is shown which includes the left side menu items only. The right side menu items on the desktop view are loaded in a different menu.
