Behavior

I browse to a category view of the blog e.g. /en/blog/category/car. Choosing another language in the language chooser does not update the slug of the category: /de/blog/category/car.

Expected Behavior

The category slug changes (and maybe the word "category' too).
From /en/blog/category/car to /de/blog/kategorie/auto.
