AFAIK, the syntax is (note the BABEL and the :session)

#+BABEL: :session *R*

With that, I can certainly reproduce what you get and it
is indeed the global session that causes it. If you
want a global session for all the other code blocks but
want to override it for the single shell block, you can do:

#+BEGIN_SRC sh :session *SH*
ls -a
#+END_SRC
