Sidemenu disappear when I click from an itemlist: is a normal behaviour?

Hello. I don’t understand if the behaviour of my app is normal.
I have a side menu with some child views: when I call this child views from the menu everything is ok, the header has the menu button.

When I call the same child view from another child view (an item list) the menu button disappear, in my header bar I have just the back button of the navigation.

Is this normal? I want to keep always the menu button in the bar.

In your menu.html file, change <ion-side-menus enable-menu-with-back-views="false"> to <ion-side-menus enable-menu-with-back-views="true">

Thank you, I will try!
