Top-down object stuck to wall

[eliris]

I am using the Top-down-movement on a rounded object.
I am using a condition: [If green ball is colliding with the wall]>[separate ball from wall]
When I move the ball with the arrow keys and it touches the wall on the left for example, it tends to get “stuck” where it stops moving, but also when I try to move right (away from the wall), it feels stuck and takes a whole second of holding the right button to get unstuck.

How can I prevent this? What could be the cause?

What happens if you add a Change Speed of object before the separate action, so it looks something like:
