Does Substance have problems with height maps in Blender?

Hi everyone,
I’m texturing a project and i found a weird problem using the height maps created in substance painter.

If I connect the height map with the bump node
the height is not represented correctly as it was created in substance painter
But if i forget the height map and instead i export from substance the OpenGL Normal map everything work good as it should.

Below the basic node setup in Blender

I also noticed that in the Height map the height information is not even represented:

Someone know something about this issue?

Thanks in advance to everyone!
