Fixed price not working

Newbie here – just purchased premium WooCommerce Multi Currency – I want to sell my product in US$ and GBP. I do not want it to convert and I have added fixed prices within my product and on the WooCommerce Multi Currency Settings I have enabled fixed price but it keeps currency converting it and not staying at the fixed price in the UK.

This is my checkout page https://ecourses.bowencollege.com/checkouts/uk-checkout-page/

Here is a document with screenshots on the products, settings and the UK checkout page converting when selected. https://www.bowencollege.com/wp-content/uploads/2019/01/Multi-currency-problem.pdf 1

Thanks in advance for your advice on what to do.
