Big Bugs with Multi Role & Custom Post Type

Hello @team,

I detect a big problem with Tutor LMS. Please check it carefully & fix it ASAP.

I have CPT call it: faq

add_action( 'init', 'register_my_cpt_faq' );

function register_my_cpt_faq() {
	register_post_type( 'faq', array(
		'label'               => 'faq',
		'description'         => 'Frequently Asked Questions',
		'supports'            => array( 'title', 'editor' ),
		'hierarchical'        => false,
		'public'              => true,
		'exclude_from_search' => false,
		'show_ui'             => true,
		'show_in_menu'        => true,
		'menu_icon'           => 'dashicons-format-chat',
		'show_in_admin_bar'   => true,
		'show_in_nav_menus'   => true,
		'can_export'          => true,
		'has_archive'         => true,
		'publicly_queryable'  => true,
		'show_in_rest'        => true,
		'map_meta_cap'        => false,
		'capability_type'     => 'faq',
		'capabilities'        => array(
			'edit_post'          => 'edit_faq',
			'read_post'          => 'read_faq',
			'delete_post'        => 'delete_faq',
			'delete_posts'       => 'delete_faqs',
			'delete_other_posts' => 'delete_other_faqs',
			'edit_posts'         => 'edit_faqs',
			'edit_others_posts'  => 'edit_other_faqs',
			'publish_posts'      => 'publish_faqs',
			'read_private_posts' => 'read_private_faqs',
			'create_posts'       => 'create_faqs',
		),
	) );
}

I update capability for role Admin like this:

register_activation_hook( __FILE__, 'my_addons_activate' );

function my_addons_activate() {
	$custom_post_type_permission = array(
		'edit_faq',
		'read_faq',
		'delete_faq',
		'delete_faqs',
		'delete_other_faqs',
		'edit_faqs',
		'edit_other_faqs',
		'read_private_faqs',
		'publish_faqs',
		'create_faqs',
	);

	$administrator = get_role( 'administrator' );
	if ( $administrator ) {
		foreach ( $custom_post_type_permission as $cap ) {
			$administrator->add_cap( $cap );
		}
	}
}

With that code, login with Admin and everything’s working perfectly.

But when an Admin user has more than a role (Admin role apply to become instructor and then approved): this user has two roles like this: http://prntscr.com/10yvqqv

And then Admin can’t add/view Custom Post Type FAQ
