Why cant my Multisport Spark 3 connect to both a Garmin Speed Sensor 2 and a Garmin Cadence Sensor 2

I have successfully connected both the Garmin bike sensors on other devices, but it only picks up the Speed Sensor2 on my Spark 3 watch. These Sensors are both Ant+ and Bluetooth LE allowing multiple connections on Ant+ and 2 connections on BLE

I also had the connection successfully on this watch to a Crane Cadence and Speed sensor combined.

The watch can only pair to one sensor, so if you want speed and cadence you would need a combined sensor, otherwise you have to choose one or the other,
