Where can I set the following genre category at KDP

[Guardian]

My book, Crystal Shade is an Epic / YA Fantasy. Now, I'm able to set the Epic Fantasy category, but where the hell I can set the following;

Kindle eBooks > Children's eBooks > Science Fiction, Fantasy & Horror > Science Fiction, Fantasy, & Magic (This is the category of the book, Cinder.).

When I check the KDP genre section, I can't see any YA, nor Children's eBooks in the Category section. As these categories are existing, see above, you can set this... but my question is where (Shelfari also doesn't have this category. At least not that I've found.).

Sorry. I was blind. It's on Shelfari. I ask a moderator to please delete this thread. Thanks!
