Your guess is completely right, there is a partial discount set on shipping cost, so a voucher code was created with the amount of this discount. Thank you pishkus

Hi there! So we have created 100 voucher codes with a script using our client's shop webservice. All went ok, but when a customer uses a voucher code and the order created, Prestashop is creating automatically a new voucher code with the same attributes except the code, which is the same but adding "-2". Any idea of what can be causing this? Thanks in advance
