Who is your domain registrar and/or DNS hosting provider?  It appears that you have it setup properly based on your screenshot, but that is NOT what is being put out to the Internet (See below).  It is REALLY messed up.  You may have to contact your DNS provider to get some answers and get some guidance on how to format it, or something, but the root of your problems is in your DNS records and how they are published to the rest of the world.
