Open is probably the test user's name that you're using. That's my best guess at least. Never heard of that.
As for it not showing on the Timeline, that's a recent change from Facebook. You can read more about the change and it's ramifciations in their bug report:
developers.facebook.com/bugs/452585014808810
We have an open comment for more clarification on the changes. You can read more about what we think the changes mean in this
Open Graph Read actions for Joomla
. There are some changes we'll be implementing in an upcoming release of JFBConnect to work with their changes as well.
Hope that helps explain,
