The key thing to note is they are the non-www versions and I only use the www and also redirect non-www to www in htaccess.
Same here. Non-www throughout. But I think it's just a bing quirk, and they really do know what you're called.
Go to the My Sites page. Does that show each name in the correct form? Mine does. And if I pull one of their recorded search terms and feed it into bing dot com, they again give the right form of the sitename.
