My org has several custom objects, but only some are displaying when I attempt to edit the OWD settings in the "Organization-Wide Sharing Defaults Edit" view.
What determines which custom objects are able to have their OWD settings edited, and which don't?

When a custom object is on the detail side of a master-detail relationship with a standard object, its organization-wide default is set to Controlled by Parent and it is not editable.
That's why those custom object does not show in the org-wide sharing.
