Coupon code not converting

HI Team,
we are using the premium plugin in our website along with the WooCommerce coupon feature. All is working fine except for coupon adapting to the currencies switching.

For example: let’s say we want to buy a product for 40 euro, and have a 10% coupon. The website displays the correct values and final price. But if we change currencies from euro to forint, the price changes correctly, but the coupon keeps the previous value of the euro and only changes the currency symbol.

Any help to solve this would be greatly appreciated.
