Sleep timer never gets activated

I'm trying to use the Shutdown Mode function in the App Settings to turn off the Vesc after certain time, however it seems like it never gets activated. Is there any setting that could prevent this function working? 

Also, I could not test, but the kickstart wakeup functin should be automatically active after the sleep?

I'm using a simple FOC controller coupled to an ADC input, nothing else. Firmware V6.02 on a Vesc 6  MK VI HP.

Thanks!
