Time delay option not working in automation

I created an automatic switch to turn my lights on and off via a motion sensor. Trivial.
It works but as people walk by the room it turns on the lights.
So I tried to add a delay of there must be motion for say ten seconds but when I selected d that option, the save menu item gets greyed out and I can add that setting.
Help.

5 seconds won’t change anything. Almost every motion detector that works with SmartThings has a “blind” time longer than 5 seconds.

Thanks
When I set it for 1 minute it still stays greyed out.
