Currency does not change at the checkout

Hi,
I just bought the plugin because you assured me that the plugin will work perfectly as I want only in the PRO version however the plugin does not convert the currency at the payment page.
When the user goes to the checkout page the currency remains in EURO but should be converted in MDL, instead of this when a user places the order, I must go to the woocommerce>>order and there manually have to change the currency in MDL, and after that to send invoice so the user could pay, only in this case is working.
check the screenshots below they all related for the same order
Thank you
