WP Job Manager plugin – Expired job missing from the XML sitemap

Does the plugin support other statuses to ‘publish’? I’m trying to enable ‘expired’ a custom post status to be listed into the xml sitemap?

Maybe the fix would be to see how can I exclude CPT’s with a custom post status ‘expired’ from the generated sitemap?

I’ve tried

function wpjm_include_jobs_in_sitemap( $filter, $type ) {

	if ( $type == 'job_listing' ) {
		$filter .= ' AND post_status = "expired" ';
	}

	return $filter;
}
add_filter( 'wpseo_posts_where', 'wpjm_include_jobs_in_sitemap', 10, 2 );

The code seem to break the post type job_listing-sitemap.xml listing only 1 link to the /jobs page. Any tips?
