wp-ecommerce tranaction detail problem..

We are receiving too many orders from same person. Check out this screen shot. http://prntscr.com/nqlhx Only one of the orders completed. Not exactly sure what was going on but it looks like we get order confirmations even when the order isn’t completed? Need to look into this. The screen shot indicates only one of her orders were completed and went through. Odd that we get order notifications for orders that were not completed!
