Reviews not showing up

I thought UserTrust was a great idea and as well as adding it to my site I have promoted it in some peer groups. However, despite having received 12 reviews so far, which I can see in my control panel, when I click on the seal I can only see 4 of them, no apparent way to view the others, and the seal on the web pages shows “not yet rated.”

Why is it not possible to see all of the reviews?
