XML : Hide toolbar on RecyclerView scroll causes text to move into notification bar

In an application I am just starting, I have a RecyclerView. I used the following code to hide the toolbar when scrolling through the RecyclerView:

  app:layout_scrollFlags="scroll|enterAlways"    

When scrolling, the toolbar moves but it's text slides into the notification tray instead of disappearing.

At the top of the image in the notification tray it says HarHar and then shows the settings button at the end.

An example of this is:

The code for the toolbar is:

   <?xml version="1.0" encoding="utf-8"?>  <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"      xmlns:app="http://schemas.android.com/apk/res-auto"      xmlns:tools="http://schemas.android.com/tools"      android:layout_width="match_parent"      android:layout_height="match_parent"      android:fitsSystemWindows="true"      tools:context="com.harhar.harhar.MainActivity">        <android.support.design.widget.AppBarLayout          android:layout_width="match_parent"          android:layout_height="wrap_content"          android:theme="@style/AppTheme.AppBarOverlay">            <android.support.v7.widget.Toolbar              android:id="@+id/toolbar"              android:layout_width="match_parent"              android:layout_height="?attr/actionBarSize"              android:background="?attr/colorPrimary"              app:popupTheme="@style/AppTheme.PopupOverlay"              app:layout_scrollFlags="scroll|enterAlways"              />        </android.support.design.widget.AppBarLayout>        <include layout="@layout/content_main" />        <android.support.v4.view.ViewPager          android:id="@+id/viewPager"          android:layout_width="match_parent"          android:layout_height="match_parent"/>        <android.support.design.widget.FloatingActionButton          android:id="@+id/fab"          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_gravity="bottom|end"          android:layout_margin="@dimen/fab_margin"          android:src="@android:drawable/ic_dialog_email" />        <android.support.v7.widget.RecyclerView          android:id="@+id/recyclerList"          android:layout_width="match_parent"          android:layout_height="match_parent"          android:layout_alignParentTop="true"          app:layout_behavior="@string/appbar_scrolling_view_behavior"          />`    </android.support.design.widget.CoordinatorLayout>    

If anyone could help I would truly appreciate it. Thank you.
