Why is my taxonomy archive content only visible to logged in users? [closed]

Question

UPDATE: Resolved

A plugin called Press Permit was auto-filtering the content types. I checked some boxes and it magically started working.

I have a custom built taxonomy. When I view the archive page for a term I see no content when I'm a normal browser, but when I'm a logged in user it's populated perfectly.

The posts themselves are published public.

What would make that happen?

The taxonomy is created with a plugin called Easy Custom Post Types. Here's the code it creates:

// registration code for svcnote_type taxonomy
    function register_svcnote_type_tax() {
        $labels = array(
            'name'                  => _x( 'Areas', 'taxonomy general name' ),
            'singular_name'         => _x( 'Area', 'taxonomy singular name' ),
            'add_new'               => _x( 'Add New Area', 'Area'),
            'add_new_item'          => __( 'Add New Area' ),
            'edit_item'             => __( 'Edit Area' ),
            'new_item'              => __( 'New Area' ),
            'view_item'             => __( 'View Area' ),
            'search_items'          => __( 'Search Areas' ),
            'not_found'             => __( 'No Area found' ),
            'not_found_in_trash'    => __( 'No Area found in Trash' ),
        );

        $pages = array('svcnotes');

        $args = array(
            'labels'            => $labels,
            'singular_label'    => __('Area'),
            'public'            => true,
            'show_ui'           => true,
            'hierarchical'      => true,
            'show_tagcloud'     => false,
            'show_in_nav_menus' => true,
            'rewrite'           => array('slug' => 'it/service-notes/area', 'with_front' => false ),
         );
        register_taxonomy('svcnote_type', $pages, $args);
    }
    add_action('init', 'register_svcnote_type_tax');
