FAQ boxes won't open when clicked - Divi theme

I am attempting to create a front facing FAQs page using the Support plugin.
I have set it up per the documentation, but the front-end does not appear to be working right.
I am unable to open the FAQ boxes by clicking them or the plus sign.
I do not see any javascript errors in the console either on page load, or after clicking. This is happening in Divi from Elegant Themes. Works fine in 2015.

Here is the page where this is happening: https://you.uark.edu/faqs-test/
Just FYI.
