Price does not match between Product Price + Options and Cart Total Price

Dear sir, we have the following problem :

– When purchasing a doll without any option, the cart price and doll price matches and is correct.
– When purchasing a doll, choosing option and changing currency, also everything is OK
–> But when we are in cart, everything that is not in USD is wrong : Doll + Option doesn’t match with total price or is even lower.
