Does not appear DocType Directory Structure

Hello, I try to create the tutorial provided by frappe, everything was fine until they ask me to add files to the doctype folder since when searching for the path there is no model file, does anyone know how I can add it?
I have already added the developer mode and clean cache but the folders still don’t appear

check in doctype list
the doctype you create doesn’t have custom? checkbox CHECKED
if it does uncheck it and save
the files will show for you

Things you have to do:

  1. enable developer mode: (which you already did so ignore)

bench set-config developer_mode 1

  1. Make sure that you unchecked the custom check in doctype
