Wierd shadow

Hi guys! I have a very weird problem with my shadows. The lighting on the cube, for example, is not sharp and doesn’t multiply. However, when I move my character onto the landscape in my scene, it creates five other shadows behind the moving player pawn. This doesn’t look natural and destroys the feeling of playing the game because all you see is a weird shadow.
