Hi Christian,
This is actually normal behavior as Joomla articles works the same way when unicode aliases is enabled(https://www.screencast.com/t/LHMwHUVo).
As a gentle reminder, kindly start a new thread if you have any other issue in the future so it will be easier for us to manage your inquiry. I will lock and mark this thread as resolved.
