1 Accordion Not Loading

We have used the Accordion plugin for a while, settings have been the same for years. 1 of the accordians is no longer working, just a spinning wheel. But all the others are still loading.

I have tested putting in another accordion shortcode and the page loads it, so it is the accordion itself and not the page.

When I make a new accordion, it loads as well but none of the style settings and custom CSS load properly.
