Focal Length Not Displayed Nikon D40 Display Screen Covered By Box?

Nikon D40 Display Screen Covered by Box? - focal length not displayed

Hello! I played with the settings on my Nikon D40 and have no idea what I am confused. Every time you take a picture, or when I checked from my camera, the screen is an area that covers the picture with the settings (shutter speed, aperture, exposure mode, lens, etc..) If anyone knows how to get rid of this arc, as their tons of relief supplies. Thank you!
