I had to do a little extra work to get subtree export to work properly. Subtree export appears to also not append ‘LATEX_HEADER_EXTRA’ to the header. I had to add the values I need to the properties of the subtree using 'EXPORT_LATEX_HEADER_EXTRA'. This actually cleaned up a lot of the code, but it was work I'd been putting off.
