Multi Currency not working with Smart Coupons

I have Smart Coupons and Subscriptions for Woocommerce both running on my site.

The problem I have is that in my country of South Korea, PayPal doesn’t accept Korean Won as a payment currency. So we have to use the multi currency plugin to allow people to switch to USD prior to paying to allow them to checkout with PayPal.

Almost everything works fine. The payment goes through appropriately, but the problem we are having with our Subscription Products is that they are each connected to a “Store Credit” coupon of varying KRW values (₩320,000 for example). The problem is that when this coupon is copied and attached to the user’s account, the “amount” of the coupon is converted to USD and then attached to the copied coupon’s amount

So a coupon that should have been ₩320,000 for store credit. Got converted to $288 and then the 288 was put into the ‘amount’ field for the new coupon and now it’s ₩288 which is less than $0.30 USD. If a coupon is a certain value, it should NOT be converted. Period.
