Loss of Supervision on Window Sensor

I dropped a window sensor six months ago and had to replace it. I affixed it to the frame in the same place as the original and it’s aligned the same as the other functioning sensors. I’m getting a loss of supervision signal yet it has fresh batteries. I’m wondering if I didn’t add it correctly to the monitoring system. It shows the window as closed on my system. It’s the north guest bedroom window.

Hello,

Was the new device working correctly when set up or is the trouble recent?
