First, I'm using Emacs 27.2 and Org 9.4.6. I have the following code in an Org file: #+latex_header: \hypersetup{pdfauthor={Author},pdftitle={Title},pdfsubject={Subject},pdfkeywords={keyword},pdfproducer={Emacs Org},pdfcreator={pdflatex}} #+latex_header: \hypersetup{colorlinks=true,urlcolor=blue,linkcolor=black} The above lines are in a section at the end of my document. When I do C-c C-x C-l in a section (or with a fragment at point), the following appears above every fragment that is previewed: pdfauthor=Author,pdftitle=Title,pdfsubject=Subject,pdfkeywords=keyword,pdfproducer=Emacs Org,pdfcreator=pdflatex colorlinks=true,urlcolor=blue,linkcolor=black Here is a sample section from my Org file: --BEGIN-- * Distance Formula Let $d$ be the distance between $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$. \[ d=\sqrt{\left(x_{1}-x_{2}\right)^{2}+\left(y_{1}-y_{2}\right)^{2}} \] --END-- Scott Randby

You probably want #+LATEX_HEADER_EXTRA, not #+LATEX_HEADER. Do
(info "(org) Latex header and sectioning")
where it says:
#+BEGIN_QUOTE
The LaTeX export back-end appends values from ‘LATEX_HEADER’ and
‘LATEX_HEADER_EXTRA’ keywords to the LaTeX header. The docstring for
‘org-latex-classes’ explains in more detail. Also note that LaTeX
export back-end does not append ‘LATEX_HEADER_EXTRA’ to the header when
previewing LaTeX snippets (see *note Previewing LaTeX fragments::).
#+END_QUOTE

That worked after I deleted the old images in the ltximg directory. I hardly ever preview LaTeX fragments, but I'm changing #+latex_header: to #+latex_header_extra: everywhere.
Thanks,

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.
