raw replace not working

[Roger Mason]

Hello,

I using Org mode version 9.2.3 (release_9.2.3-390-gfb5091 @
/home/rmason/.emacs.d/org-git/lisp/) in GNU Emacs 26.3 (build 1,
amd64-portbld-freebsd11.3, X toolkit, Xaw3d scroll bars).

Here is an ECM:

#+begin_src shell :results raw replace
#!/usr/bin/env zsh

mkdir -p Supercell
for i in 1 2 3
do
    touch Supercell/111_stuff.cif
done
ls Supercell

#+end_src

#+RESULTS:
111_stuff.cif
111_stuff.cif
111_stuff.cif

Is there something I'm doing wrong or is this a limitation of org 9.2.3?

Cheers,
Roger
