Farmland Middle-Mouse Click

I middle-clicked on wet farmland and I got a weird kinda dirt in my inventory. When I placed it I got a missing texture.

What I expected to happen was...:
I get farmland in my inventory.

What actually happened was...:
I got a weird kinda dirt texture in my inventory. It said Dirt & Building blocks but when I placed it down, It gave a missing texture.

Steps to Reproduce:
1. Get a WET Farmland.
2. Middle-Click the farmland
3. Place it down.
