Only some posts display

Using the widget to feed from https://www.facebook.com/NZWebFest/ to https://www.nzwebfest.co.nz

I (page admin) and 1 editor do most of the posting. When I post on fb as admin, it doesn’t feed into the widget. When the editor posts on fb, it does feed into the widget.

I tried the jetpack fb widget as well, and that gives the same result. Editor’s posts feed into the widget, admin’s posts don’t. Is there a solution/workaround to this issue, so that all the page posts feed into the widget?
