PayFast Plugin Is Forcing Default Currency To Show At Checkout.

Hello. So I recently bought CURCY and I am experiencing an issue. I am using the Woocommerce PayFast Gateway and one thing I have noticed is that it is forcing to show the default currency at checkout. And when I set the US$ checkout currency under Checkout tab to “YES”, the payment gateway does not work in the frontend. It says “No billing method available for your country”. When I set it to no, the payment gateway will work but it will show both the US$ and the default currency. Is there a rule I can set to bypass this so that it shows the US$ from beginning of the checkout process to the end? I have tried different combination of settings but I am not getting it right. Please help.
