This is the expected behavior. The kitchen node uses "instant seal" which means that blocks will only be authored when transactions are sent. Open up Polkadot JS and try to send some tokens or make some other transaction. You should see blocks authored immediately.

Yes, of course. I understand now, "Idle" means "I'm synced and waiting for something to do"..
The confusion started because in the original seminar video, the console showed different feedback.
Thank you for your time.
