Magento 2.4.1 switches back to default language

We have the problem that in Magento 2.4.1 by clicking the Homepage link it switches back to de default language. All other links are keeping the language.

Example:

  1. Default Language DE
  2. Switch Languae to US -> OK
  3. Click on Homepage Link -> Switches Back to DE
  4. Click another Link -> Switches Back to US

Is that normally or an issue?
