This seems to be a symptom of the same issue as http://lists.gnu.org/archive/html/emacs-orgmode/2016-10/msg00175.html
A workaround is to put the contents of the #+BEGIN_EXPORT ... block into a separate .org file (include.org), and #+INCLUDE it in the main document #+INCLUDE: "include.org" export <backend> where "include.org": * Heading other text On 03/11/2016 11:47 AM, Lixin Chin wrote:
As per the subject, when a heading line is included within a `#+BEGIN_EXPORT backend ... #+END_EXPORT' block, it breaks the parsing of the block, which is instead split into multiple `paragraph' elements. See the attached example (test.org), and associate exports (test.tex) and (test.html). Tested with `emacs -Q -l minimal-org.el', with the org package installed from http://orgmode.org/elpa/, org-20161102.
