I only have sensors on the rear, and I'm pretty sure the Columbus used to show just the back of the car with the warning markers............

Now, engaging reverse brings up an image of the whole car with detection markers all over the shop. I believe the audio guidance is still working correctly

Anyone had this anomaly?

Mine has allways shown the whole car as soon as I engage reverse or manually activate the sensors.

How do you manually activate the sensors?

Presumably thats a reference to the front sensors? IIRC there is a button on the gear lever surround for that.

Top right button at the gear lever. Used it just 5min ago. PS - for me, it activates all sensors.

It should show just the rear of the car if you only have rear sensors fitted.

Engaging reverse or pressing the button activates all sensors: front & rear (obviously only if fitted).

Try rebooting your Columbus.
