wrong prices and currency

I have a currency problem.
In practice, on the page https://www.leadmobile.it/index.php/listino-e-commerce/ it shows me the products with the wrong prices. It shows me the prices in dollars but with the euro symbol.

Here the screenshot: https://i.ibb.co/hYbwjRF/screen.png

For example BASIC STORE would cost €50 not €54.99
