This is because, when you set num:nil, Org exports headings to LaTeX
using the \section*{} command, not the usual \section{}.  LaTeX does not
put sections defined with \section* (or \chapter*, \part*, etc.) in the
table of contents. 

Thus, if you still want all sections to show up in your table of
contents, you probably don't want to set num:nil.  If you just want
section numbers not to show up in section titles, there's probably a
simple way to do this in LaTeX by redefining a command, but I can't find
it right now; maybe someone else here knows.  Once you know the LaTeX
command, you can set it on Org via

#+LATEX_HEADER: \renewcommand{...}

or whatever.

I'm not sure about this issue.  I would guess that it's also caused
by using \section* rather than \section, but there's no \leftmark
command in the test document I created.
