El Capitan changes language input after reboot

every time I restart my Mac (OS X El Capitan 10.11.3), the language input is set to "ABC Extended" instead of English or German. This causes me trouble when I want to type my password. Is there a way to set this back to English or German?

These are the keyboards I have installed.


Solution 1:

One workaround is to open System Preferences -> Users & Groups -> Login Items and enable "Show input menu in login screen".

After enabling the checkbox you can choose between several input sources in the upper right corner.
