Screen Time is counting while locked

Hi All,

I like to keep my Mac idle. So if I don't use it I just lock it and let it turn off the screens. Unfortunately this does not stop the Screen Time counting for the open applications. This results in me having 24h Screen Time of the Finder or something like this.

Is there something around this? Does it count while sleeping? Should I set an auto-sleep to kick in after some minutes to stop this?

Best regards,

Tell
