Is it ok to have Abstract view within a Abstract view seems to mess up navigation

1

I have the following routes :

    .state('home', {
        url: '/home',
        abstract: true,
        templateUrl: 'app/home/home.html'
    })
    .state('home.search', {
        url: '/search',
        views: {
            'home-search': {
                templateUrl: 'app/search/search.html',
                controller: 'SearchCtrl',
                controllerAs: 'vm'
            }
        }
    })
    .state('home.options', {
        url: '/options',
        views: {
            'home-search': {
                templateUrl: 'app/search/options.html',
                controller: 'OptionsCtrl',
                controllerAs: 'vm'
            }
        }
    })
    .state('home.multi', {
        url: '/multi',
        abstract: true,
        views: {
            'home-search': {
                templateUrl: 'app/search/options-tabs.html',
                controller: 'MultiOptionsCtrl',
                controllerAs: 'vm'
            }
        }
    })
    .state('home.multi.address', {
        url: "/address",
        views: {
            'home-search-subtab': {
                templateUrl: 'app/search/options-address.html'
            }
        }
    })

with a default of

$urlRouterProvider.otherwise('/home/search');

and back buttons set up :

      <ion-nav-back-button class="button-clear">
          <i class="ion-arrow-left-c"></i> Back
      </ion-nav-back-button>
      <ion-nav-buttons side="left">
          <button menu-toggle="left" class="button button-icon icon ion-navicon"></button>
      </ion-nav-buttons>

If I navigate from home.search to home.options the back button shows and left menu icon is hidden.

But if I navigate from home.search to home.multi.address the back button is hidden and left menu icon shows.

How come it doesn’t follow same logic ?

Edit : here is also the options-tab.html, I have a feeling the fact that I want to load a sub view is the problem here.

<ion-view class="home-search padding" padding="true">
    <ion-header class="bar bar-subheader options-tabs">
        <div class="subTabs">
            <a class="tabsItem" ui-sref-active='active' nav-transition="none" ui-sref="home.multi.address">Address</a>
            <a class="tabsItem" ui-sref-active='active' nav-transition="none" ui-sref="home.multi.business">Business</a>
        </div>
    </ion-header>

    <ion-content class="has-subheader inner-content padding">
        <ion-nav-view name="home-search-subtab"></ion-nav-view>
    </ion-content>
</ion-view>
