[Gelöst] Checkout page translation that is built using WooCommerce Checkout Field Editor

Hi.
I am trying to translate my checkout page. I am using the plugin WooCommerce Checkout Field Editor, but the fields and labels don't translate. I tried string translation, but I don't find them. And I also tried looking in the plugins' settings. Can you help me?
Thank you!
