Add multiple post types?

Hello, I am trying to add two post types to my WordPress. I used the following code in my functions.php file and only the first one “Web Design” is working.

if( ! function_exists( 'portfolio_post_types' ) ) {
	function portfolio_post_types() {

		register_post_type(
			'web-design-portfolio',
			array(
				'labels' => array(
					'name' 			=> __( 'Web Design', 'web-design-portfolio' ),
					'singular_name' => __( 'Website', 'web-design-portfolio' ),
					'add_new'		=> __( 'Add New', 'web-design-portfolio' ),
					'add_new_item'	=> __( 'Add New Website', 'web-design-portfolio' ),
					'edit'			=> __( 'Edit', 'web-design-portfolio' ),
					'edit_item'		=> __( 'Edit Website', 'web-design-portfolio' ),
					'new_item'		=> __( 'New Website', 'web-design-portfolio' ),
					'view'			=> __( 'View Website', 'web-design-portfolio' ),
					'view_item'		=> __( 'View Website', 'web-design-portfolio' ),
					'search_items'	=> __( 'Search Websites', 'web-design-portfolio' ),
					'not_found'		=> __( 'No website found', 'web-design-portfolio' ),
					'not_found_in_trash' => __( 'No websites found in Trash', 'web-design-portfolio' ),
					'parent'		=> __( 'Parent Website', 'web-design-portfolio' ),
				),
				'description' 		=> __( 'Create a Website.', 'web-design-portfolio' ),
				'public'			=> true,
				'show_ui' 			=> true,
				'show_in_menu' 			=> true,
				'publicly_queryable'	=> true,
				'exclude_from_search' 	=> true,
				'menu_position' 		=> 6,
				'hierarchical'		=> true,
				'query_var'			=> true,
				'supports' 	=> array (
					'title', //Text input field to create a post title.
					'editor',
					'thumbnail'
				)
			)
		);

		register_post_type(
			'graphic-design-portfolio',
			array(
				'labels' => array(
					'name' 			=> __( 'Graphic Design', 'graphic-design-portfolio' ),
					'singular_name' => __( 'Graphic Design', 'graphic-design-portfolio' ),
					'add_new'		=> __( 'Add New', 'graphic-design-portfolio' ),
					'add_new_item'	=> __( 'Add New Artwork', 'graphic-design-portfolio' ),
					'edit'			=> __( 'Edit', 'graphic-design-portfolio' ),
					'edit_item'		=> __( 'Edit Artwork', 'graphic-design-portfolio' ),
					'new_item'		=> __( 'New Artwork', 'graphic-design-portfolio' ),
					'view'			=> __( 'View Artwork', 'graphic-design-portfolio' ),
					'view_item'		=> __( 'View Artwork', 'graphic-design-portfolio' ),
					'search_items'	=> __( 'Search Artwork', 'graphic-design-portfolio' ),
					'not_found'		=> __( 'No Artwork found', 'graphic-design-portfolio' ),
					'not_found_in_trash' => __( 'No Artwork found in Trash', 'graphic-design-portfolio' ),
					'parent'		=> __( 'Parent Artwork', 'graphic-design-portfolio' ),
				),
				'description' 		=> __( 'Create an Artwork Piece.', 'graphic-design-portfolio' ),
				'public'			=> true,
				'show_ui' 			=> true,
				'show_in_menu' 			=> true,
				'publicly_queryable'	=> true,
				'exclude_from_search' 	=> true,
				'menu_position' 		=> 11,
				'hierarchical'		=> true,
				'query_var'			=> true,
				'supports' 	=> array (
					'title', //Text input field to create a post title.
					'editor',
					'thumbnail'
				)
			)
		);
	}
}

add_action( 'init', 'portfolio_post_types' ); // register post type
