Yes, that's by design.

I recommend that you click the "Help" button in the Language Support window for a description of how it's supposed to work. Since English is always available, a list with fallback languages would be pointless, wouldn't it?

No, that's a misconception. If you change the user language from Dutch to English and log out, you end up at the login screen. If you log in again instantly, you should see English as the display language.

The display language of the login screen, OTOH, is controlled by the _system_ language. If you change that, you do need to reboot.

As regards Chinese, there is a known issue, i.e. if you have Chinese installed, the menu item doesn't disappear if you remove it. As far as I know, there is no similar problem with German.

Could you please execute the command

  ll /usr/share/locale-langpack

from a terminal window. If the output includes a 'de' folder, German is installed.

If you don't see a 'zh_CN' folder, you are right about Chinese. In that case, you should be able to make the Chinese menu item go away by running this command from a terminal window:

  sudo locale-gen --purge
