Woo Multi Currency and book your travel theme

Hi,
I have a problem with the plugin. On the archive product page, the currency switcher works fine. When I try to rent a car, in the product page, in the Availability tabs, the prices are right, but after I click “Proceed” and it redirects me to the Cart page, the prices are totally wrong(my product costs € 51/day and on the cart page it shows € 2.14). An this happens only if I have the currency plugin activated.
Can you help me, please?
