First, I'm using Emacs 27.2 and Org 9.4.6.

I have the following code in an Org file:

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:

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--

where it says:

‘org-latex-classes’ explains in more detail.  Also note that LaTeX

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.
