Duplicate Transactions / After Payment Has Been Successful Orders Are Disappearing

When customers are making payments with debit or credit cards, orders are duplicating with different order number. We are occuring this error almost every 100 orders. Our developers have not found what is the problem.

Orders are right after another, but it was charged with same card less then a second from each other. And it was also charged at the same credit card.

During this error, first orders disappears and left with only the second order. For example: if customer's intention was to order '1234', system automatically creates '1235'. After order '1234' will get deleted and only left with '1235'. But for customer credit card it was charged twice for both orders.

We think that if payment has been made by customer, CS-Cart keep data of orders at first then delete the orders that does not corresponds with the payment. But even if this happens, it should not be charged double.

Also, there are orders with only one payment and gets deleted from the database, and Orders process twice and both orders are deleted.

Any help would be appreciated.

Thank you.
