Order showing up multiple times

-- url of the page with the problem -- : www.BestederNewsletters.com

-- Error-message(debug-mod must be tuned on) -- : Error_message

I'm experience seeing an order show up multiple times in the system in the LAST 7 ORDERS section. But they don't show up multiple times when I view the orders from the regular orders area. Is this something I should be concerned about?

Great Thanks!
