Daskeyboard 5Q does not switch off

For the last two days I notice that the keyboard lights stay ON after I shut down the computer (not even in standby).
I do not know for how long it has been doing this as I normally walk away from the PC once I shut it down.
Firmware v28.31.0 connected
Version 4.2.1

How can I make sure the lights go off when I shut down the PC.

Kind regards,
Jan
