I thought it would have the wooden walk-on sound, the ability to be broken by hand, the ability to be broken by an axe, and not be a retextured stone slab.

Well, I placed down a wooden slab, when I tried to break it it made the sound of breaking a stone slab, when I placed it, it sounded like a stone slab, and it was unbreakable by hand. Not even axe. I had to use a pickaxe.

Steps to Reproduce:
1. Craft a Wooden Slab.
2. Place the wooden slab (Hear the stone placing sound).
3. Try breaking it with anything but a pickaxe.
