I have this setup in my Orgmode doc and it doesn't export the author affiliations to latex or pdf. Instead I get a heuristic 'immediate' in place of authors I have added Latex to Org -babel-Load languages in .emacs What must be done to allow babel to evaluate Latex code blocks? Is there a hyperef setup that I must change? Is there an easier way to do it without a latex code block?
