Child posts not displaying in content template

Hi,

I have a parent CPT called 'AMC Entity' and a child CPT called 'Opportunities'.

I have a view set to display a list of the child (Opportunities) posts of the parent (AMC Entity). The 'Opportunities list' view uses the 'Post relationship – post is child of’ filter. This view is placed in the content template view for the parent CPT. I know the child posts are associated with the parent post because they are listed in the parent post's Field table. I am receiving the 'No opportunities found' message on the parent CPT page but not the child CPT list.

Any thoughts? The page is: http://com-cam.org/amc-entity/school-of-dental-medicine/

Thank you
