[Closed] URL Slug not updating on language switch

Background of the issue:
I am trying to change the language from English to German/French/Italian on my website. However, while navigating to the sub-categories, the product-category slug in the URL is not getting translated, resulting in a 404 page. The issue can be seen at this URL: hidden link. The specific URL where the problem occurs is hidden link, where 'product-category' should be 'produkt-kategorie'.

Symptoms:
When switching languages, the product-category slug in the URL is not translated, leading to a 404 error page instead of the expected accessories sub-category page in German.

Questions:
Why is the product-category slug not translating when switching languages?
How can I fix the 404 error caused by the untranslated slug?
