[Gelöst] The string `Your cart` doesn't appear translated on the front-end

Background of the issue:
I am trying to translate the string `Your cart` on the front-end of my website. I found the string under the domain: woocommerce-wc-blocks-mini-cart-contents-block/title-label-frontend-chunk. When I change this setting in the Theme Customizer (Shoptimizer), it changes in the above string and on the front-end, but it only appears in English. The issue can be seen on this page: versteckter Link.

Symptoms:
The text `Your cart` appears in English in both languages instead of being translated to `Je winkelwagen` in Dutch.

Questions:
Why is the string `Your cart` not translating to Dutch on the front-end?
How can I ensure the string appears in the correct language?
