New Outdoor Camera Picking Up Reflections

We installed a new version of the Outdoor on our vacation home a few weeks ago. It is constantly picking up vehicle motion in a window, even though we have that window grayed out in the activity zone. We also have never had a problem with this happening on the older model xt2 or the original outdoor model cameras (we’ve been around a long time with blink). I’ve tried moving the camera slightly, adjusting the activity zones, sensitivity, everything I can think of, but I’m getting 10+ clips a day of basically nothing and it’s super frustrating. Any suggestions? Or do I need to put an older model camera in this spot?
