Soul campfire doesn’t deal twice the amount of damage as normal campfire

The bug

The new soul campfire deals exactly the same amount of damage as normal, but soul fire deals twice the amount of damage so I think that soul campfire is supposed to deal twice the amount of damage as normal.
How to reproduce:
1. Place a soul campfire and a normal campfire.
2. Stand on both types of campfire.
3. Compare the damage that you took from them.
You will notice that soul campfire deals exactly the same amount of damage and not twice the amount.
