bed textures misplaced/mixed up

Basically when you have a bed placed down in the world,
When placed North to south, the mixed up textures are on the east
When placed East to West, the mixed up textures are on the north side
The textures are: left: A side texture with the bed leg on the right the,
right: the texture looks like it's been flipped from left to right
the mixed up textures always have the same texture
this happens with and without resource packs

What I expected to happen was...:
the textures should be the right way around

What actually happened was...:
The bed's textures on the side were mixed up/mis mached

Steps to Reproduce:
1. Place a bed down in the world, either direction will do
2. if its N-S look at the two east textures, they will be mixed up
3. if its W-E Look at the north side and the textures will be mixed
