Landscape Layer Material not working

I just update my project from 5.6 to 5.7 and it won’t allow to paint the landscape, I made a layered material to my landscape and when I try to paint any of the material to the landscape it just looks like is doing it but it still showing also the previous material that I’m trying to paint and hide, is making some kind of weird blend and it was working fine in 5.6

In case anybody is having the same issue, the problem was that unreal is not working with the Layer weight blending, now it says legacy and is not working in order for it to work we need to clear it from the material and create a No weight blending which doens’t allow any tyoe of blending between layeres, I don’t know the differences between then and why UE took it off but I liked the other way because it allows me to create nice blend between layers.

Now I found the problem with the method, is that it won’t let me paint any other layer in top, that was the whole point of working with layers, So this new type sucks
