Did you go through this with the checkout wizard? If so open up the confirm page and try to edit the Universal Email server behavior that is on that page. You should be able to see the options specified and check on the body. If you cannot get the email updated like this properly post back with a copy of your confirm page minus any sensitive details and the webassist folder from your site root in a zip archive. I can take a look to see why you would be getting this in the message body.
