Sub-Categories (Walk around)

Hey, i've seen a couple of posts with sub-categories, and looks like we are not going to get them any time soon, so i was thinking about walk around and tried to make empty category, and it worked! BUT non admins can't see them.

I've made empty categories without channels and used them as dividers (pic 1). But if i choose allowed role which can see this category, it won't show it to me (pic 2). 

I wrote to support asking if it's a bug or feature, but they said "it is what it is". Mine discord supposed to be a "home" for my university class (180 people) but somehow i can't make it look easier for them to navigate. 

Thank you, for your attention! Have a great day!
