Custom Query Widget & Multiple Pages : No page options to select from

Hello – I was fine following steps of creating the Full Screen Sidebar as in “Enlightenment Documentation: Deconstructing the Theme Demo Home Page”, but came to the stage of ‘Adding the Custom Query Widget’ I seemed to have found myself in need of your guidance.

So please help:

The Custom Query Widget does not show any page as options in the box below ‘Select Pages:’. Of course I selected Slider and 1 Column, Multiple pages as for other options.

I tested other types i.e. Gallery with Multiple Pages and got the same, no options.

Any ideas?
