Executing "Select Block" on Farmland Causes Weird things to happen

I middle-clicked on farmland, wanting dirt, and i got dirt, I got id 3/7 which was an invalid block. Its texture was the side of a dirt block taking up the entire block in a 2D state. When i tried to place i got the broken pink and black invalid texture. Also happens with any dirt block spawned with a data value higher than 3
