Are you trying to make an 8-direction movement that also has jumping? Because this isn't the right way to go about it. You shouldn't be using platform behavior for this, it gives weird results when jumping while moving up or down.
I'd talk to Arcticus about how to make things jump in orthographic perspective. He might be able to give you some ideas.
As for what's colliding with what, I don't know what's broken because I don't know what you're trying to do here. Is the "tec" object always supposed to collide with the blue box? Or just when it's not jumping? Because when I'm jumping I can pass through it, but only sometimes. Otherwise, it's always solid.
