I wonder if that's similar to the question I asked as a followup to
the link I sent you to:
- https://lists.gnu.org/archive/html/emacs-orgmode/2013-03/msg01583.html

Did you try :wrap as well? I was having issues with :results org as
well and found out that the prior recommendation to use this was
updated to :wrap org instead...

I didn't try :wrap, but I did try :results wrap (which is what that post suggested) which did nothing different as far as I could tell.

 

Out of curiosity... is the "%s" syntax related to python
(unfamiliar)... just noticed how you did that and wondered if that was
via Org/emacs/babel or via python.

That's python syntax. 

Glad you found something that worked!
