I'm using Emacs 25.1 and the most recent orgmode. My problem is that I tried compiling one of the examples on Worg, but the content that's supposed to be displayed in a block is displayed on its own slide:

** A more complex slide
This slide illustrates the use of Beamer blocks. The following text,
with its own headline, is displayed in a block:
*** Org mode increases productivity :B_theorem:
:PROPERTIES:
:BEAMER_env: theorem
:END:
- org mode means not having to remember LaTeX commands.
- it is based on ascii text which is inherently portable.
- Emacs!
\hfill \(\qed\)
Did I miss something? Or is the example simply outdated, and I have to do something else?
