I saw that someone posted the same issue a year and a half ago, but never got an answer.

We use this script on another page on the website, and it works.

The issue can be seen at https://writebrainbooks.com/book-builder-plain_dev.php?prodid=322&bid=61aC7gAL7Z&refid=11584

I ended up replacing the include.js, and that fixed it.
