The correct currency symbol does not appear in the cart

Hi, I just installed and configured the plugin in euros (default) and dollars. At first everything seemed to work correctly, but suddenly when you enter the cart and select the dollars, all the prices appear with the euro symbol (€) even though it correctly converts the price in dollars. This error can cause confusion, since I need that when the price is in dollars, it appears with the $ symbol and not in euros. How could I solve it?

Thank you very much!
