What's this about?  Are you loading parts of Org in your init files,
directly or indirectly, and is the version of Org in
.emacs.d/elpa/org-20150810/ the one you call "org 8.3" above or some
older version?

And these say you have one more version of Org, under
/usr/share/emacs/site-lisp/.  What version of Org is that?
