Urgent fix for when “fixed price” is enabled

Hello, I currently use the extra product options with woocommerce and that where we set price. When I enable the fixed price, set the prefered rate in usd it doesn’t show the set price in usd when I switch from naira to usd.

I have put the webssite on maintenance mode and we had to pause running ads. I will appreciate if you can treat this urgent.

Kindly help me look into this issue.

Cheers
