Height Blending with Landmass Blueprint

HI, I’m trying to build landscape using Landmass Blueprint Brushes. My issue is that when I’m editing weight maps from the blueprint they act as if they were in separate Edit Layer than anything else, so when I use Weight-Blend I have the “half transparent” issue for the layer … So I’ve read that the solution for this is to use no weight blend + alpha blend, that works, but then I can’t use height blending.

Can I somehow use Height Blend with Blueprint Brushes?
