The "scoreboard objectives setdisplay list" command isn't working

When I try to create any type of scoreboard list, it doesn't appear in the left side of the pause menu. I usually use scoreboard lists for level displays in a world, and now in my current world, where this command worked as intended before this update, doesn't work. I made a sample world to make sure the issue wasn't just because of a command error, and upon doing everything in the correct manner, the list never shows up.
