Looks like the user moved it from their blog namespace and incorrectly moved it to the "Blog" namespace.

You should be able to delete it by adding "?action=delete" at the end of the URL. Such as here.

For the second one, you might not want to delete it due to the history (I'm assuming it was a valid article). So I would rename it back without leaving a redirect.
