Strange Approach CT10 issue with Driver

I have the strangest issue with the CT10.

All sensors added and working well (1 month old).

The sensor on my Driver abruptly stopped working. Could be re-added, re-assigned.

I got the sensor from my 6 Iron and re-assigned it to my driver successfully.

After one or two drives the next time I played, the driver sensor stopped working again.

The clubs live in the bag (sensor down), are brand new (I had a replacement sent by Garmin) and nothing seems to work.

When I tried to re-assign the driver sensor back to the 6 iron, it wouldn't work. It's like the driver completely kills the sensor?

I know how ridiculous this sounds however to have the same thing happen twice in a week is very strange.

Would love some ideas.
