Bed Texture glitched (Only Red/White part)

So I just installed Minecraft 1.7.2, I load up my world from 1.6 (I did load every place needed before in 1.6.4) And then I headed into my house and the texture for the top half of the bed glitched. It is only glitched on the side of the bed that you place it at. I will attach a few photos of it.
