I am working with 'Node form columns 7.x-1.x-dev (2011-Feb-25)' & 'Menu attributes 7.x-1.x-dev (2011-Feb-25)' -- http://drupal.org/project/menu_attributes.
After updating and installing a few modules, there occurs a display of 'Menu item attributes' on 'admin/structure/types/manage/foo-nodetype/form', suddenly from nowhere! From my point of view, this display should not happen.
On top of that, when I try to hide this attribute [for node creation purposes], it still shows up. Related issue here:.
