2d collider wrong detection

[bytasdelen]

Hello everyone,
I have a problem In my game there are blocks(2d box) and balls. (blocks have 2d box collider, balls have circle collider.)
When I fired my balls they work in abnormal pyhsics.
When the ball goes through the red arrow way, generally it continues to go yellow arrow way but sometimes it goes though green arrow way. I think ball collides both the first box and then the second box and it comes back
How can ı fix it?

Thank you.

I would have just one box collider covering all four boxes on the left and just one other box collider for the four boxes on the right.
