Unforutnately, your elements are hidden inside comment tags.  Here's what I'm seeing on the page when I perform a "View Source":

The comment tags are "".  They're usually used to hide content from rendering on the client-side.  Learn more about HTML comment tags here: http://htmlhelp.com/reference/wilbur/misc/comment.html

Not sure why you'd contain these valid elements within comment tags, but that's why SEOmoz can't see them. I'd suggest that this is also not best practice for Google and other search engines, even if they've managed to extract them.

So: remove the two comment tags from your elements and you'll be back in the clear.  Cheers!
