Fixed prices are not being displayed on product pages

I am using Shopify markets… My default currency is euro for various markets. However, in the Romanian market the currency is RON. I have fixed prices set for this market. The fixed prices are correct on my collection pages however, as soon as you click on a product the prices revert to the converted EURO price in RON, so the prices are all incorrect. As soon as you add the item to the cart it is the correct price. However, it is obviously a problem as inconsistent for the customer. I am looking for a fix for this problem?
