Permission, hide "post setting" without losing the ability to edit posts

I'm restricting the access for a user that will act as an editor (delete, create and modify any content on the website).

The problem is that I can't seem to hide "post setting" (http://imgur.com/KQBtw.jpg) without losing the ability to edit content.
I know it's trivial but I would like to understand if it's possible to hide that section. The permission are these:

->admin module
use admin toolbar

->node module
access content
administer nodes
create * content
delete any * content
edit any * content
(* = multiple content types)

->node_service module
load node data

->system module
access administration pages

everything else is not checked. It appears as the "Post Setting" must be shown if you allow to manage content.

Thank you very much for your help
