CONSTANT Guardian sensor requests for BG?

I have the Guardian sensor, and for the most part I love it. But I’ve noticed that often after I’ve put in a new sensor (like I did this morning), the pump will repeatedly give me the BG required message for Auto Mode - like, sensor is calibrated, it requested a BG to go into auto mode, I just entered a BG, it says “processing BG”, and then says it needs a new BG again! Three or four times in a row! Sometimes it then tells me calibration is required too, even if the sensor is fully calibrated, before entering auto mode.

Do other people experience this? Has anyone found a way to make it stop? Or is this a bug that needs Medtronic’s involvement?
