[Gelöst] Translate loop item on product page

Background of the issue:
I am trying to translate the buttons of my loop item on the bottom of my product pages. The issue can be seen on this page: versteckter Link. I expected the buttons to be translated as they are in the same loop item on the archive page versteckter Link and the homepage versteckter Link.

Symptoms:
The buttons in the loop item on the bottom of the product page are not being translated and remain in the original language.

Questions:
Why are the buttons on my product page not being translated?
How can I ensure the buttons on my product page are translated like they are on the archive and homepage?
