Always in Center is not in Center

Im implementing the always in center style and i can't get it to be centered. Whats weird is if i rotate landscape then back portrait it is then centered like it should be.

<com.ogaclejapan.smarttablayout.SmartTabLayout
            android:id="@+id/tabs"
            android:layout_width="match_parent"
            android:layout_height="48dp"
            android:paddingBottom="4dp"
            app:stl_indicatorAlwaysInCenter="true"
            app:stl_indicatorWithoutPadding="false"
            app:stl_indicatorInFront="false"
