When my friends and I play a game in creative and they try to place a block it will only put down stone. Example when they try to put down a torch, wood, or another item, it will place stone. I don't know if this is only us but its a problem.

I expected them to place wood not stone.
It was odd to me because every item they tried to put down it was stone not the item they wanted to.

1. Join a game on someone else's world.
2. Place down any block except stone.
3. Wonder why it placed stone...
