Icon size of bottom navigation view in tablet version

[pablouu]

I have a bottom navigation view:

<android.support.design.widget.BottomNavigationView
android:id="@+id/bottomNavView_Bar"
android:layout_width="match_parent"
app:itemIconSize="@dimen/design_navigation"
android:layout_height="match_parent"
android:background="@color/colorBackground"
app:itemTextAppearanceInactive="@Style/BottomNav"
app:itemTextAppearanceActive="@Style/BottomNav.Active"
app:labelVisibilityMode="labeled"
app:menu="@menu/bottom_navigation" />

So, i created a tablet variation of the layout of the menu:

the text area over the icons, and i can't move the text further down.

I created a dimension file to tablet

46dp but doesn't works
