Incorrect amount added to cart (conversion occurs incorrectly)

Steps to reproduce: Go to product URL.

Make sure currency is USD (Change at the top right where it says SRD).
Enter the required amount as 50.

Expected output in basket: USD 50
Actual output in basket: USD 2.10 (which is the equivalent of SRD 50).

A currency conversion occurs here when it should not.

Please advice how to fix.

Note: the “enter required amount” field sets the price that the user wants to pay for the item. It is part of the “advanced-product-fields-for-woocommerce-extended” plugin. Upon debugging that plugin, it correctly shows the value as 50 being added to cart, but your plugin is changing the currency when adding to cart.

Caching: we are using autoptimize, don’t think this has an impact. Please feel free to deactivate and test.
