The other content is what breaks it. The page must start with #REDIRECT link. I'm not sure if having the content there makes it show up in the preview under the Read More header on articles. But since redirects shouldn't be showing up there in the first place, the safest thing is just to remove all content, leaving only the redirect code. Also, redirects should never be in categories.
