Unable to enter price with correct currency

Hi, I am using name your price add on for Woocommerce.

My site is based in Mexico and we take payments from Mexico (MXN) and USA (USD)
Site is in two languages (Spanish and English)

I have set different currency for different languages and that works fine. However, when I set the price for the name your price product in English (even though the description displays USD) when I enter the amount the checkout page displays the price in the original currency MXN.

I’v try everything to make this work and I cant seem to find the answer anywhere.

Also I try to create a product (Name your price) only in english to see if that will solve the issue, but the product in English also gets the rate in MXN but with the difference that on checkout is displaying in USD but with the amount rated as is I enter the information in MXN

To sum up, when the product is duplicated with Polylang and I enter 100USD, on checkout I see 100MXN.

When product is only in english and not linked to an Spanish product and I enter 100USD, on checkout I see 0.01USD (Base on the rate that is enter)
