Multicurrencies based on Polylang language doesent work

Hey
I bought this plugin because I have a multilingual webshop. I’m using polylang and one of the reasons I bought this plugin is that I can switch currencies base on the polylang language.

After I installed, activated and set up the plugin I cant set or change the regular product price (Macedonian denar MKD) nor the translated products (Dollars $). Every entry field is blocked. I provided an image file so you can see the actual problem.
