Summary: Unable to create smooth stone from stone using a furnace.

What I expected to happen when I put stone in the furnace with coal was, the stone to smelt into smooth stone.

However when I put coal in the regular furnace  with stone nothing happened.

To reproduce this bug place down a furnace with stone and give the furnace coal.  From some further checking this only occur with stone that has been smelted from a prior update, it turns out that the stone is acting as if it is andesite, see image below.
