Bullet goes through obstacles. Need help!

I'm trying to make a platformer type game. I'm using the free version of Clickteam Fusion 2.5.

The problem I have right now is that I want the bullet to be destroyed upon colliding with an obstacle, but it still goes straight through the obstacle as if it weren't there.

The obstacle type is set to obstacle, and everything is on the same layer, but the bullet is still going through it.

What am I doing wrong?
