Prestashop displays doubled cost of the ordered product on the back office

[Call_me_Dave]

Hi,

I have this this issue concerning the order section of my Prestashop Dashboard. There in the order section the price is displayed correctly, but when I click on the name of the customer who paid for that product then Prestashop redirects me to the page with order details, where the ammount of money paid by the customer is doubled. This problem is occuring only on the back office and it applies for every possible type of payment. Please help.
