High CPU useage Cerbo GX when changing I/O analogue

Hi all
I have a bug in the Cerbo GX.
I have three victron temperature sensors.
One is going faulty (this is not the problem), I went into the I/O, analogue and disabled Temp input 2, so that I’m not seeing this input on Red Node or VRM.
When I have done this the Cerbo GX cpu stays around 75% useage.
If I enable this input on the Cerbo GX the CPU drops down to 35%.
I have rebooted Cerbo GX with the same result.

Do you have anything else loaded on the gx that is referencing the temperature sensor? Nodered etc?

As per above this temp sensor is an input to node red (set to send change only)

If you temporarily disable nodered but leave the sensor attached, what happens to cpu usage?
