Im dumb and cant figure out how to add categories to Individual levels. I just submitted TEMBO THE BADASS ELEPHANT and I started adding stuff to the page. I added any% to the full game categories, but when I created a level, and tried adding any% to level categories it kept telling me any% was already taken. Ive seen other games have any% for both full games and IL's, so what am I missing?

Sorry about that, you're not missing anything: it's a bug currently. It's supposed to only prevent people from creating multiple IL or multiple full game categories with the same name, but it doesn't check fullgame vs IL properly.
It'll be fixed in the update coming out in one of the next few days, but for now I've added the category for you manually.

Thanks. Ill refrain from setting up the other IL's until its fixed.

There shouldn't be any problems with settings up ILs, as long as you avoid naming IL categories the same as full game categories.
Adding the levels themselves should work just fine.
