In Billing Info >> Display Currency
I have selected the currency Dollar.

But the site always goes back to displaying the value in BRL (Brazilian
Real) on the purchase page of a book or in the cart. II change it, but it always comes back again whenever I visit the en.logos.com page and return to the logos.com page in English. This happens in the Edge and Chrome.

I prefer to keep everything displayed in the payment currency, which is the dollar.
