If I go to the Black Ops 2 Zombies leaderboard (https://www.speedrun.com/bo2zombies) I only see a fraction of the categories, sub-categories, etc that should be visible [image 1]. I can successfully tap on the "blank space" confirming that the categories are still there, and bizarrely I can zoom in to reveal the categories bit by bit [images 2 & 3]. I'm experiencing this on a couple of game leaderboards, but not all.
