Fine-Tuning Ball Collision Physics

I’m trying to change how a ball bounces back after colliding with a wall:

If you open the “Rolling” project template, you can use the WASD keys to control a ball rolling through the level. If the ball has a somewhat higher speed and collides with a wall, it does not only get pushed back into the direction it came from, but also upwards - the ball does a little jump.

While this might be physically correct, I don’t want the ball to jump like that. I already tried to modify various parameters like the bounciness of the ball and the floor but could not find a solution.

Is there a way to customize the materials or other parameters to prevent this jump?
