I recently installed CDP and noticed that the navigation buttons (prev, next) changed to text, how do I get the buttons back?

Also, I'm not sure if this is related but I would also like to have buttons for tell a friend and write a review, how do I have buttons display instead of text?

Here is a link to the page.

Any help would be appreciated.
