Express Checkout on checkout page bypasses shipping only to countries

Hello
I run my woocommerce until now with the following option :
– shipping only to selected country (only one)
– selling only to selected countries (3-4 countries)
In this case, it was only possible to place an order with a shipping country that corresponds to the selected one. On the checkout page a click on the “proceed to payment” button scrolled up the page to the error message saying “unfortunately we don’t ship to that country”.
I recently installed your plugin to add the express checkout payment gateway on the checkout page. But I found that it bypasses the country check when express payment is chosen and the “proceed” button is clicked it directly goes to paypal page and don’t scroll up to the error message.
