Issue in selected payment Currency

Hello ,

I have installed the plugin ad add USD, AUD and NZD currency. USD is default currency.
When we select AUD or NZD and go to checkout we can see the total amount with correct selected currency, but with total amount we can see this line . (You will be billed: $95.00 USD )
I also Attached screen shot of the checkout page. Also when we did payment the payment received in USD not in the selected currency.
Here is the URL of website https://www.zipcushions.com/

looking forward for the help

Thanks
