And how did you create it when it's illegal?
Usually this happens when namespace names change, so that formerly it
didn't start with a namespace prefix but now it does. Since both
namespace names in this case are canonical and will always exist, I'm
not sure how it came to be.
Pages named "Talk:NS:Foo", where "NS" is a valid namespace name, used
to
be allowed until fairly recently, but they never worked particularly
consistently. See
