Problem with falling in 2d side scroller

Hello everyone I have a problem to get my character fall from a certain height, I was moving all the parameters but I could not solve it.

When my pixel character falls from the second platform (the one that is highest) to the largest, the character falls correctly.
But when the character falls from the platform closest to the ground, the character does not fall, the character teleports automatically to the Ground ignoring all the route that must do in Z.
The problem is solved if I move the platform upwards, which makes me think that there is some kind of Snapping.
I would like to know how to solve this problem in another way, I do not want to move the platform. Thanks in advance.

I’m sorry if my English is not very good, I’m learning.
