I have this same issue.
And I have a functioning 301 redirect in place from non-www. to www.
"same" = wmt lists both versions of the site?
Sometimes an issue is just an issue ;) It's not a problem. Check periodically to see if anyone is linking to the "wrong" form of the name, especially if it's a site you're on speaking terms with so they'll fix it if you ask.
