Disable Shipping Convert

Hello!

I’m using a woocommerce in brazil, but the products are all imported from the USA. So this plugin will help me a lot!

My problem is this: I’m using a plugin to calculate shipping and it uses the Brazilian currency, and this plugin is understanding that the shipping is also in dollar and is doing the conversion.

That is, a shipping that would cost R$100, is costing R$330.
It’s converting R$ to R$ as if it were US$
($1 = R$3.30)
