App Store Categories HELP

I have an iPhone 5S with iOS 10

I remember opening my App Store before and have 2 lines of categories for action games and adventure games. I'm not exactly sure hat happened but now it has Games>Action games and as a 2nd option gave me the main category for kids. I must have downloaded a kids app for my son back then but now all my suggestions comes up as kids games.

I guess my questions are as follows;

1.) Is a user stuck with only 2 categories for suggested apps?

1.5) If so. Can a user not have 2 subcategories for suggested apps under a main category?

2.) How do i remove KIDS as a main category from my App Store main page
