When in Survival and in Creative or any game mode,I would break the door or hit it, and It would produce white particles, and when I would place double doors they would face the same day, but will open like they are supposed to.

What I expected to happen was...:
Wood particles to come off the door, even when it broke. And the knobs to face to each other.

What actually happened was...:
White particles came off when broken or hit. Knobs didn't face each other. (CHECK PHOTOS)

Steps to Reproduce:
1. Place double doors
2. Break or hit the door
3. Watch the white particle fall
