Hi Chuck,
It looks fine to me. I see:
Name: fig:foo
Lang: python
Properties:
:header-args :eval never-export
:header-args:python nil
Header Arguments:
:cache no
:eval never-export
:exports results
:hlines no
:noweb yes
:results file replace
:session discharge_ts
:tangle no
-k.

That is the right idiom. Of course, you have to refresh the local setup after typing that (C-c C-c with point in the PROPERTY line) or it will have no effect until you save and re-open the file.
It is good to check that you have refreshed and that there are no typos or hidden chars in the line, so go to a src block and type
C-c C-v C-i
and verify that you see something like this

You should see both the :header-args line as you typed it and the :eval line showing never-export.

Leave it set to `t'.
