Sure, here's the presentation.org from the website, which does have that
OPTIONS line.  It produces no blocks for me:

#+LaTeX_CLASS: beamer
#+TITLE: Example Presentation
#+AUTHOR: Carsten Dominik
#+LaTeX_CLASS_OPTIONS: [presentation]
#+BEAMER_FRAME_LEVEL: 2
#+BEAMER_HEADER_EXTRA: \usetheme{Copenhagen}\usecolortheme{default}
#+COLUMNS: %35ITEM %10BEAMER_env(Env) %10BEAMER_envargs(Env Args)
%4BEAMER_col(Col) %8BEAMER_extra(Extra)
#+OPTIONS:   H:3 num:t toc:t \n:nil @:t ::t |:t ^:t -:t f:t *:t <:t
