Not sure, we haven't seen that before. Can you explain a little more about what that is? It looks like a stream story. Is that in a friends feed, or a friends post in your own feed? I'm assuming you don't already like that page?
We'll look into this a little, but my guess is that it's an automatic feature from Facebook. JFBConnect doesn't have too much control over feed posts *from a Page*. We can manipulate posts (Likes, Comments, Open Graph Actions) that come from your website, but for posting to content to your Page, that's something that's pretty much 'on' Facebook.com itself.
Hope that helps explain,
Alex
