I having troubles with the intial setup.

From the documentation...Setting up the Home page...Step 2
" 2 Create the Feature Posts Slider: Add a Page List block to the Feature area. Under Number and Types of Pages select Article page type. Under Filter, select Featured Pages Only"

..then.... "(if you haven't created the Featured attribure yet, go to Dashboard->Pages and Themes->Attributes and create a "check box" attribute with the handle is_featured and the name Featured). "

My issue - The Feature attribute (2nd part of this step)
When I go in to set up the feature attribute i do not see the "Check Box" (in drop down list) attribute to create.

Am I missing something? Any help direction appreciated.

Using # concrete5 Version 5.5.2 # concrete5 Packages ViewPort (1.0).
