when I open the detail page of a product (in my English version of the page) and click “Add to cart” the quick view of the shopping cart opens up from the right side. In this quick view I see the values in German language though – also see screenshot. (when I open the shopping cart quick view by clicking on the shopping bag icon on the top right after opening it the first thime via the “add to cart” option everyting is visualized in German as well but when I open it via the icon before I use the “add to cart” button or after refresh I see everything in English).
Please let me know in case you need more infos. Thanks!
