TIMER SHUTDOWN not working-QSHUTDOWN and GSHUTDOWN

Applications QSHUTDOWN and GSHUTDOWN do not shut down computer in CHALET, although in
Ubuntu and Mint they work as they should. Gshutdown at least does a little bit of the job in CHALET as it logs out into Lock screen and then you still need to shutdown manually, so still nothing is done actually.

I tried few settings and it's the same.

Is there any fix or setting for that?
