Where the magnets attach to the screen

Where the magnets attach to the screen, the light is now distorted and seems to be coming through images on left side/bottom side of screen. I have an IPad Pro, 12.9, second generation and the keyboard is Apple and it has been swapped out by Apple bc the design of the former keypad was poor and stopped communicating with the IPad. Now after many months, this replaced by Apple keyboard has ruined my screen.
