Amenities Options and Create listing errors V9

How do i change the amenities options? most of them do not apply to the directory i am creating so don’t want them to show. Also, when creating a listing, if i have custom fields based on the category they don’t show up because when creating a listing selecting the category is the 3rd option after media and description. Should what category you want the listing to appear in come first so any custom fields you want to show based on the category are immediately visible when the description/opening hours etc are then selected?
