Select from CPT items in Menus

I’m going nuts trying to figure out why I cannot select from my Custom Post Type entries in the menus are under Appearance. I’ve checked the Screen Options tab at the top…everything.

Any ideas?

register_post_type('products', array(
'label' => 'Products',
'description' => 'Company products',
'public' => true,
'show_ui' => true,
'show_in_menu' => true,
'show_in_nav_menus' => true,
'capability_type' => 'post',
'hierarchical' => true,
'rewrite' => array(
'slug' => ''
'query_var' => true,
'exclude_from_search' => false,
'supports' => array(
'taxonomies' => array(
'labels' => array(
'name' => 'Products',
'singular_name' => 'Product',
'menu_name' => 'Products',
'add_new' => 'Add Product',
'add_new_item' => 'Add New Product',
'edit' => 'Edit',
'edit_item' => 'Edit Product',
'new_item' => 'New Product',
'view' => 'View Product',
'view_item' => 'View Product',
'search_items' => 'Search Products',
'not_found' => 'No Products Found',
'not_found_in_trash' => 'No Products Found in Trash',
'parent' => 'Parent Product'

Shouldn’t this work? The CPT behaves normally …I just cannot select from its added items in the Menus area of WordPress. It would seriously suck to have to add each menu option manually. Not only for me, but for the client to maintain as well.
