Ionic back button between side menu items


I have an ionic side menu with

When i open the side menu and click ‘about’ I am brought to the about view as expected and the hamburger menu is still on the menubar (this is what I am expecting)

Now from the about view if i open the side menu and click on home i am routed to the home view BUT the hamburger icon is replace by a back button which routes to the ‘about’ view.

My question is how do i prevent back button from appearing when i am just transferring from one side menu item to another?
