Material normals are blank in the Dynamic Layered Material workflow

1.Open new project
2. switch shader to pbr-material-layering or pbr-material-layering-10-mats
3. assign all materials to any material that has distinct normal map(e.g. Stylized Wood Bark)
4. Normal map is visibly blank/totally flat - bug

interestingly enough, while no materials in the basic library work, some materials from substance 3d assets do work, this one for example :
