I’m using two keyboard layouts, German (QWERTZ) and German (neo).

I’d like to be able to switch between these two using the Super+Space shortcut. However, that only works for switching from QWERTZ to neo. When the current layout is neo, Super+Space does nothing.

On the other hand, when I’m in neo, Shift+Space does switch the layout, but it’s not supposed to.

How can I fix these two issues?

These are my keyboard settings from the system settings UI:
