Paypal Pro payments that have exact match avs get shown as fail in cs-cart

Hello



I am using cs-cart version 2.1.1



I have noticed that some Paypal Pro payments that have exact match avs get failed by cs-cart. So I get a customer say why their order failed, then I check on paypal site but the order has gone through fine with an exact avs cvv2 match M



So for some reason sometimes cs-cart 2.1.1 puts the orders into failed state, is this a bug?



Thanks
