When I go the the IL leaderboard, it shows four categories for each level. Which one do I submit my runs in?

What do you mean ‘IL leaderboard’

Individual levels. It shows four categories for each level

There are 4 levels for each area, every area has 4 levels

But there are 64 total leaderboards, not 16. For example, there is an ammo hills - 1 ammo hills%, ammo hills - 1 gunpowder cave, ammo hills - 1 deagle dreamland, and ammo hills - 1 Mt. Combustion.
