Rearview camera only with beam in the picture?

Moin, the image of the rear camera is restricted by a warning message in a yellow bar. That also means that the last 10 cm of all are hidden?! The service employee finds it “unhappy”, but doesn’t look like this to change in the warehouse. With our X-Trail a similar indication fades out after 2-3 seconds. Does anyone have a solution to this problem?
