Platform Effector 2D One Way, not working as expected

I'm been using the new platform effector 2d with the one way check box.

I have some problems

1- i have to change the "Collision detections" to continous in all the characters with rigidbody2D attached to them, if i don't do that i get stuck on the one way platform if i fall from high on the platform.

2- if hi hit the one way platform in his sides , my character doesn't go throw the platform as expected , he hits againt it like an normal BoxCollider2D.

¿is just me , or the one way platform has some issues?

PD: sorry for the poor english , not my main language.
