[Geschlossen] Language switcher sync probem

Background of the issue:
I have a page where I have 3 different languages (Swedish, English, and Dutch). On the Swedish and English pages, the language switch works between these two languages. However, the Dutch alternative just gets me to the home page. But on the Dutch page, the language switch works like it should. It shows that the connection between the pages is correct but something else messes up.

Symptoms:
The language switcher on the Swedish and English pages redirects to the home page when selecting Dutch, but it works correctly on the Dutch page.

Questions:
Why does the language switcher redirect to the home page when selecting Dutch from the Swedish and English pages?...
How can I fix the language switcher so it correctly navigates to the Dutch page from the Swedish and English pages?
