Problem with Pathfinding

Hello,

I'm trying to learn construct2. For learning purposes I start creating simple logic game. But I have problem and I can't solve this. I attached example project. I set for 'Ball' sprite Pathfinding behavior and set it to not move diagonally. But sprite is moving diagonally. Another problem is that ball sprite is move over obstacles even when is surrounded by obstacles. Thanks in advance for help and directions how to solve this problem.

[Edit] Change example to better one. (Still not working)

I Can't see why your ball sprite is moving diagonally because I'm currently at work. however, I can give you some advice about your second issue. ¿Do you have assigned the obstacles the behavior Solid? your sprite should not move through obstacles with that behavior.
