Translated product shows wrong basic price

I am running Woocommerce Multilingual Plugin in combination with Woocommerce Product Price by Country Plugin (PBC). I created the products in my basic language, which is German, and translated the products using the Multilingual Plugin.

For the pricing I am using the multi-currency functionality of the PBC plugin. My basic currency is EUR. When I switch from German to English, the products show different basic prices, which should not happen. You can check this on the following website: https://www.torland-fashion.com/shop/. Switch the language with the dropdown menu in the top right corner to see the change of prices!

There is no possibility to edit the prices of the translated products, because the Multilingual Plugin should copy the prices to the other language. How can I correct the wrong prices of the translated products?
