There are a couple of level/story packs missing in the Level Leaderboard, is it possible that they can be added. Also maybe check the capitals in the level names, sometimes it has capital letters, sometimes not, it triggers me a little bit. :')

Also the level packs have their own names for their levels, so is it possible to change it to the actual names: "Portal 2 level pack" -> "Aperture Science"

So all the level packs are there I have added in story packs and have changed the capitals on the level leaderboard, as for the names it seems that they are more commonly referred to just as level packs more than anything else and also the name makes sense so I think keeping them the way they are now will work fine.
