Price is not converting from Yen to other Currencies

Hi Villatheme:

1. The default price of this product in Yen10,000 in USD it must be $67.
When the customer tried to order in this checkout, the price is in $10,000. It is not converted. Why?

We are using Funnelkits, they said that we must update the plugin but after we update the issue is still there.
