RWD One Page Checkout Progress Block Duplication Issue

[Negan009]

Recently upgrade my site to the RWD theme, however when a customer goes to checkout, the progress block (in the sidebar) seems to duplicate itself for every step of the checkout (Billing Info, Shipping Info, etc). I imagine its a js issue, but I am not the best with js so I am having an issue tracking it down. Anyone have any ideas?

Is this on a public site that we can check out?

Is there anything customised in the theme or an extension that modifies this area that could do this. Trying to return as much back to the default RWD will probably help to eliminate this problem.
