ANT Device Numbers

Why do I get this apparent contradiction? In a Garmin EDGE computer, in Sensors/About, it lists the 752963 value. So what is the 32067 value? This same conflict between two different DEVICE NUMBERS occurs for other sensors too, like Speed, Cadence, etc.

class MyRadar extends AntPlus.BikeRadarListener {

====================

   RadarSensor.getDeviceState().deviceNumber = 32067

    function onMessage(msg) {
        var payload = msg.getPayload(); //get the data payload

        msg.deviceNumber = 752963
