Two prices with different currencies in order list in woocommerce.

I have the order list in woocommerce with two prices in the Total column. The web site is configure to sell only in Peruvian Soles, but it shows the total amount in USD and then, in red, shows the amount in Peruvian currency. this is misleading since all the sales are in “Soles” (Peruvian currency). I am afraid the system might be charging in USD or that the Dashboard might be adding the totals in this conversion, from USD to Soles.
