Ion-side-menu icon not hidden when back button is showing

ionic-v1
1

I’m making an application that contains a right lateral menu by which I navigate to different parts of the application .

I have an initial view , through which I can also navigate to different views.

If I navigate from the side menu (side menu ) and the back button disappears and only see the icon menu , which is perfect . However, the back button and icon lateral menu if I sail from the initial view appears .

I tried adding " enable- menu- with- back- views" but not working . Leave the most important parts of my code to see if I can help .
