Scoreboard list slot does not display properly. My husband is running a lan on his computer for me to play with him. When hitting tab to bring up the player list, it no longer displays the objective value when it used to. This is what he did:

/scoreboard objectives add test1 dummy

/scoreboard objectives setdisplay list test1

/scoreboard players add <playername> test1 50(obviously 50 is a random number)

By hitting tab, we can view the list slot / playerlist. Unfortunately, the value for test1(obviously 50) is not displayed.
