When one names a block type using the anvil and it is placed and picked back up it is not named anymore.
I thought that after I named, the pumpkin for example, it would stay named after I wold pick it up.
What actually happened is that when I picked it up it reverted to it's previous name.
1. Take block to anvil and name
2. place block on the ground
3. Break block and notice the name has reverted to original
