State/ province for payment?

Hello

Getting this error when customer in India trying to complete the order with paypalstandardpro plugin

2019.05.17 08:39:06:1866*******
Error. GetApprovalUrl approvalUrl=
- Payment error: PayPal error: Invalid request - see details (VALIDATION_ERROR)
- Payment error: state Required field missing

Seems the problem is State property which is not included to the request, however Nopcommerce 3.80 doesn't allow to specify States for on US customers

PayPal wants to see the state for the USA.
It's important!!!

PayPal has the list of countries with necessaries state/province value.
