The connecting fence bar does not use the appropriate textures

What I expected to happen was:

When placed in the world the birch, spruce, dark oak and acacia fence connections to be the right texture

What actually happened was:

When placed in the world the birch, spruce, dark oak and acacia fence connections use the oak connection textures

Steps to Reproduce:
1. Place birch, spruce, dark oak, and acacia fences so that they connect
2. Notice the connections are not the correct texture
