Categories
  No categories

Also, I'm trying to populate it using get_categories() but still same problem, it outputting as if there were no category

Answer 1

You can use wp_list_categories or get_categories, just pass hide_empty = 0 to it. This will get you even those categories which do not have any posts associated with them.

Ex: $cats = get_categories(array('hide_empty' => 0));
