HomeKit Motion Automation has lights blinking when they shouldn’t

First a note about categories: Why can’t I choose HomeKit? None of the very many categories I can choose from is right for this problem. If you know how to direct me to the correct forum, I’d value that advice.

And now the issue: I have many HomeKit devices. Among them are Lutron Caseta dimmers for the lights and Eve motion detectors. Most of my automations are running just fine, but in my Kitchen, I’m having issues. The room has a set of 6 recessed lights controlled by a single switch which I installed this week and named “Kitchen Lights.” The motion detector is also new, and I named it “Kitchen Motion.”

At first, I set up a single rule to turn on the light when motion was detected with an automatic shut off 15 minutes later. I programmed the motion detector to continually indicate motion for 60 seconds whenever triggered. Then I noticed that as the 15 minute point came (I was continually in the kitchen), the lights would turn off and back on and off and on. I attributed this to the automation running multiple times simultaneously, so I changed the programming.

Now I have the motion detectors set to indicate motion for 10 minutes after being triggered, and I have two rules. The first is to turn on the lights upon motion being detected (with Turn Off set to Never). The second is to turn off the lights when motion is not detected. I still occasionally see the blinking effect. It only happens within the 10 minute window, but my presence in the kitchen doesn’t matter. I’m stumped.
