Command Blocks allow you to set the command but when you open them back up they do not display the previously entered command. 

What I expected to happen was...:
When you access the command blocks console after entering the command it is supposed to display the command that was previously entered.

What actually happened was...:
Command block still works but you cannot review what was previously entered.

Steps to Reproduce:
1. Place command block
2. Set command.
3. Open the command blocks console again and the command is not displayed.
