Moving character doesn't collide with a sprite placed on the map

Hi! I’m making a *Breakout *clone as a way to learn basics of UE and Paper2D in particular. I’ve managed to get most of it working, but I have one issue: For some reason the movement of the paddle ignores the collision of the borders of the level.

Paddle is a PaperCharacter with collision set to “Pawn”. Walls are set to “BlockAll” and they are clearly blocking the ball, so I’m not sure what’s happening.

Could you help me?

Thank you in advance!
