Xaiomi window/door sensor cycles between open and closed

This MCCGQ11LM device is mounted on a window
When the window opens, the device goes from closed to very briefly open to very briefly closed to open. It does the same thing when the window is closed

I have another sensor set up on the window next to this one and it works fine

This is the Zigbee device Signature. It is exactly the same for both devices.
