Torches don't Attach to NPC Torch Posts

I was creating a new superflat world and went over to a village and noticed that the torches weren't connected to the post. They were floating next to it.

I expected the torches to be attached.

The torches floated instead.

Steps to Reproduce:
1. Create a new superflat world.
2. Make sure it has villages.
3. Look at the torchposts in the villages.
