That means that something failed to settle with the order but the customer was still notified that the order was successfully placed. You should review the order and notify the customer if it was indeed placed or cancel it. Also notify Shopping Cart Elite is you find something unusual.
If you accept Paypal Pro sometimes Paypal will not return us a confirmation message that the order was settled so we don't know 100% if it was or not, so it remains as Abandoned - Processing.
