Title: Update xml-news-sitemap-class.php

$original_source = trim( wpseo_get_value( 'newssitemap-original', $post->ID ) );
if ( !empty( $original_source ) ) {
echo '' ;//issue in head, has no output, If left blank it stays blank, that is why removed.
} else {
$sources = explode( '|', $original_source );
foreach ( $sources as $source )
echo '';//issue in head, it outputs the Post Permalink instead of original source one
}
