How to switch off motion detection for light on Spotlight Cam

I'm using Ring Spotlight Cam wired and can not disable the light. My setting is "light off", mode available and in the configuration motion detection is disable. This works for the camera but not for the light. On every motion the light switches on. I switch it off in the app, check the settings (and all are set to off and no motion detection) but on next motion it switches on again, Any idea how to solve this? Many thanks!
