ok, unfortunately that seems like a Duck Duck Go bug. Not sure a good way to resolve this short of dropping the DNS alias, letting the search results be broken in Duck Duck Go for a while, and letting it age out. For comparison, a Google search returns releases.ubuntu.com (correctly); and searching for www.releases.ubuntu.com points back to releases.ubuntu.com, *and* shows this very bug report as the third result, so it's pretty clear www.releases.ubuntu.com isn't being widely referenced.
