Expected Behavior:
When two coquina slabs are placed on top of each other to make a full block, it should create a coquina block.

Actual Behavior:
When two coquina slabs are placed on top of each other, it creates a coquina bricks block.

Minecraft:1.12.2, Bewitchment:0.0.22.43, Forge:14.23.5.2854, Patchouli:1.0-20, Baubles:1.5.2

Screenshots:

This is actually deliberate behavior, but if I have to push out another update, I could change this. Though this is unlikely on 1.12, and this block is being moved somewhere else entirely on 1.16+.
