Unable to hide title in Twenty Eleven header

I recently used the codex directions to resize the header in Twenty Eleven. The header image resized to 980 x 120 just fine but now the blog title and description text cannot be hidden.

The website is https://www.carmenamato.net.

Here is all the current header code from the functions.php file

Thanks in advance!

$custom_header_support = array(
		// The default header text color.
		'default-text-color' => '000',
		// The height and width of our custom header.
		'width' => apply_filters( 'twentyeleven_header_image_width', 1000 ),
		'height' => apply_filters( 'twentyeleven_header_image_height', 288 ),
		// Support flexible heights.
		'flex-height' => true,
		// Random image rotation by default.
		'random-default' => true,
		// Callback for styling the header.
		'wp-head-callback' => 'twentyeleven_header_style',
		// Callback for styling the header preview in the admin.
		'admin-head-callback' => 'twentyeleven_admin_header_style',
		// Callback used to display the header preview in the admin.
		'admin-preview-callback' => 'twentyeleven_admin_header_image',
	);

	$args = array(
	'width'         => 980,
	'height'        => 120,
	'default-image' => get_template_directory_uri() . '/images/header.jpg',
	);
	add_theme_support( 'custom-header', $args );

	if ( ! function_exists( 'get_custom_header' ) ) {
		// This is all for compatibility with versions of WordPress prior to 3.4.
		define( 'HEADER_TEXTCOLOR', $custom_header_support['default-text-color'] );
		define( 'HEADER_IMAGE', '' );
		define( 'HEADER_IMAGE_WIDTH', $custom_header_support['width'] );
		define( 'HEADER_IMAGE_HEIGHT', $custom_header_support['height'] );
		add_custom_image_header( $custom_header_support['wp-head-callback'], $custom_header_support['admin-head-callback'], $custom_header_support['admin-preview-callback'] );
		add_custom_background();
	}
