Custom fields won't be removed from Users Content-type

I have added custom fields to the User content-type (Created by users-permissions plugin). Then I decided to remove these fields. But after removing them they still created with new objects. Here some details:

  • The user content-type contains only one field which is authorID.
  • The User.settings.json file under /users-permissions/models/ doesn’t contain those fields.
  • This is a created User:
  • The scholarID, UserID and author are the old fields that I have removed using the admin panel.
