I see the same behaviour as well.
For anyone who needs this critically before its updated and fixed, the following in your theme can be used to display it where needed:
echo(get_post_meta(get_the_ID(), “_subtitle”, true));
Add this to your functions file.
// Get rid of text before comment box.
add_filter( ‘comment_form_defaults’, ‘remove_pre_comment_text’ );
function remove_pre_comment_text( $arg ) {
$arg[‘comment_notes_before’] = “”;
return $arg;
}
