Layer in material is black

Hello everyone! I made 3 layered materials (blue, red, white) with the same settings. But 1 material has black layer.

I tried to change parent layered material, delete layers, change blend asset and material looks fine. This layer instance used for another materials and it works fine too.

I made new parent material with the same nodes.

And replaced parent material with a new version. It works for “red” material, but “blue” and “white” materials renders with erorrs.

What can I fix in the materials so that all 3 variations start working? UE 4.27.2
