Error in the display of the rear view camera

Hello, I have a problem that has been bothering me for a long time.

I have a 2020 Octavia MK4 Scout and I'm finding that the reversing camera isn't displaying in full screen.

The only difference from the rest is that it shows me "HU small" instead of "HU Large", but if I change it the camera stops working and errors start popping up.

Does anyone know what could be happening and how to fix it without having to go to the dealership?

Thanks!
