[Gelöst] multicurrency not keeping the currency

Contesto del problema:
I am trying to use the WooCommerce multicurrency plugin. When I change the currency on the product page, it works correctly. However, when I add the product to the cart and navigate to the cart or any other page on the website, the currency resets to the default one for that language. I have 3 currencies set up with English. Link to a page where the issue can be seen: versteckter Link

Sintomi:
The currency resets to the default one for the language when navigating to the cart or other pages after adding a product to the cart.

Domande:
How can we solve this issue?
