facebook like showing font code etc
 

Hi could someone just advise in my item description I use WYSIWYG editor to setup font and size etc, when I was testing facebook "Like" button on face book it was adding description but like this

<p> <span style="font-size: 14px;"><span style="font-family: verdana,geneva,sans-serif;">Shoot past admirers in these pants and youll leave them wanting more! Made from space-age liquid metallic lycra.</span></span></p>

How can i stop this from happening, also sometimes it doesn't show the picture

Can someone help please thanks
