Menu Not Sticking on Custom Page Template

Using a child theme with twentythirteen.

Menu sticks OK on regular pages.

Created a simple page template for my home page. Menu does not stick when I use this template.

<?php
/*
Template Name: Page Full Width - No Sidebars
 *
 * The template for a page in full width with no sidebars
 *
 * This is the template that displays all pages by default.
 * Please note that this is the WordPress construct of pages and that other
 * 'pages' on your WordPress site will use a different template.
 *
 * @package WordPress
 * @subpackage Twenty_Thirteen
 * @since Twenty Thirteen 1.0
