Views Block not displaying

I have a question on view blocks not showing up using the Drupal module, Context.

My Setup:
I have a block display showing a list of children pages for a specific page.
I have the Node Hierarchy and Context modules installed and enabled.
I want to show a listing of children in a side column for a section. For instance, if I'm in the About section, this block would display all the children pages of the About page on a side column.

The Issue:
Block display of the View nodehierarchy_children_list doesn't display! All other blocks display as expected.

Please refer to the following pages:

This is a child page in the About section. There should be a child listing block on the right. All other conditions (highlighted menu is highlighted, blocks are displaying for this section) are showing up, so the Block view is the only thing that is not working.

This is the landing page of the About section. The child listing on this page is an embedded view.

HELP! Any suggestions on why this is not working? What am I doing wrong?
