Panel replacement, sensor showing open

Very recently replaced a dead IQ2 with an IQ4. Sensor restoral process went smooth except that I’m seeing a sensor showing as “open”. It’s a power G sensor with an aux wired window pain mounted shock sensor. Any reason this would show “open”? This was not the behavior when paired to the IQ2.
It shows under the list of active sensors on the app.

Which sensor is it? I don’t see any window sensors currently showing Open.
