Why doesn't my Category appear on the home page?
If your category doesn't appear on the home page but you have elements in it, most likely elements that belong to this category are not actually set to be 'visible' on the home page. http://prntscr.com/9lwjjx
If a category has no visible elements, then that category is not displayed on the home page. So if we you make your elements visible, the category should appear automatically.
