LaTeX fragment preview weirdness

[Scott Randby <srandby@gmail.com>]

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--
