Problem with WooCommerce custom field with plugin WC Fields Factory

Hi,

im messaging you beacuse of a problem I have on website im creating. Its eshop trough WooCommerce. The thing is currency switching works on every aspect of the eshop but not when it comes to WC Fields Factory field – flat fee is added for this field for example if user chooses one checkbox the price is bigger by 250 (in current/default currency). But problem comes when I switch the currency. The fee is still 250, which is not good. Im using Czech Crowns – so the default fee is 250K?. Second currency Im using are Euros. So the price after switching should not be 250 but 10€ an so on. Can you please help me?
