"Rule isn't valid:Select a page and try again."
Administrators of Facebook pages have the option to set restrictions to Facebook pages such as restrictions based on age and country. When a Facebook page is restricted it cannot be added to Social Engagement under New Search Topic | Add rule | Facebook pages rule.
This is by design. The Facebook pages rule allows to capture all conversations on a public Facebook page. The Facebook pages rule will not allow to capture data which is not public.
