Toolbox does not show my descriptions and module titles

I’ve created my own modules, for example this new module, begins with that code:

<?php
/*
Module Name: KUNSTBLOG-Snippets für NEWSCAST
Description: KUNSTBLOG-Snippets für NEWSCAST
Author: BCH
Author URI: http://der-kunstblog.de
*/

/* Sicherheitsabfrage */
if ( !class_exists('Toolbox') ) {
	die();
}

Problem:
it does not show up in the plugin’s settings, there’s just a blank white field (I’ve created 2 new modules, so 2 blank fields are there):

Any idea?
Thanks.
