display

I have a 2020 Jeep Sahara and only have had it 6 weeks. Suddenly, the display is showing a battery icon and voltage, which goes up to 14.2 or 14.3. Did I accidentally select something?? Or is something wrong? Because there is also a notification beep/ding.

The display works as usual, but this strange spot keeps growing and growing. There was no reason for this spot to appear, moisture did not get in, there were no extreme temperatures either, perhaps the usual sun. Has anyone encountered this?
