custom toolbar

Hello

I try to add a custom toolbar to edit my content.
I have edit the file ckeditor.config.js like this

// Toolbar definiton for all buttons
Drupal.settings.cke_toolbar_DrupalFull = [
  ['Source'],
  ['SpellChecker'],
  ['Undo','Redo','Find','Replace','RemoveFormat'],
  ['Table','HorizontalRule','SpecialChar','Iframe'],
  '/',
  ['Font','Bold','Italic','Underline','-','Subscript','Superscript'],
  ['NumberedList','BulletedList','-','Outdent','Indent','Blockquote','CreateDiv'],
  ['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'],
  ['Link','Unlink','Anchor','Linkit','LinkToNode'],
  '/',['DrupalBreak', 'DrupalPageBreak']
];

When I am on the setting page admin/config/content/ckeditor/edit/Full (Full HTML) I well see my custom toolbar. I save the configuration and when I try to edit a content page in Full HTML I have an another toolbar.

What is my mistake ?

Thanks in avance
