Deepslate Lapis Ore isn't working with PBR textures.

Minecraft RTX's PBR textures are great all around, and I can change them in any way I so desire. Except one. Deepslate Lapis Ore. No matter how I edit the json, mer, and normal files the block continues to not use the provided PBR textures. It acts like it doesn't have any PBR files.
