Incorrect price is coming through to my stripe payments.

I have my set up as not a fixed price and entered all the rates and exchange rates (I also tried this with the fixed price on) with the default currency as AUD where I am located. However, when the money comes through the check out it is far less than the actual price of the product. For example, an $8.00 item was purchased for $4.91 from someone in Portugal and $5.52 for someone using USD.

Please help as this is very urgent – I have tried using USD as the default currency on both fixed and not fixed price and I still have the same issue. I am using the paid version of the plugin.

Thanks
