Categories in wrong language still visible for crawlers

Hi

I have a multilanguage site and categories for English and German articles. I set the language option of those categories as requested and assigned articles to it. If viewing the page in English or German the categories that shouldn't be visible aren't displayed in the list of categories. So far so good. But when entering the German category name in the English URL the category is still going to be displayed.

Example:

• English URL with English category name (should work like that): https://www.moveyourass.fit/en/blog/categories/nutrition
  
• English URL with German category name (shouldn't work): https://www.moveyourass.fit/en/blog/categories/ernaehrung
  

This situation generates issues when auditing the page in my SEO checker.

Besides, when not manually selecting the language-specific categories for the frontpage menu item, all articles will be displayed in both site languages, even if they are assigned to categories that shouldn't be displayed in this language.

Is this normal behavior or am I just doing something wrong ?

Thank you and kind regards, Stefan
