Collision problem in a pong clone

Paddle is set to block all dinamycs, and simulate physiscs without gravity, it’s a pawn with floatingpawn movement, and no physiscs enabled that moves with add movement input. The ball has same physiscs settings except for simulate phyisics that is enabled. Finally the bounds have a box collision component, that is set to block all and not to simulate physics. All have generate hit event set to true. I have noticied that the ball collide just with top and bottom bounds but not with side, and this even at start or after collision velocity (that is lower than the initial one)
