Wrong Country Code

So I am having a few customers a day, randomly – let us know that at checkout, they are not able to check out because the country code is invalid. The customers are in the US and we are receiving plenty of other orders. We havn’t been able to isolate a browser issue or replicate the issue, but they continue to have the issue. We have 2 payment options Paypal standard and paypal advanced. Both options don’t let the patient checkout due to the invalid country code.

Any advice or other people experiencing this issue? afraid we are losing sales with the people that don’t reach out to us.
