Filterable Post Not Functioning

I’m having trouble with the Filterable Post widget. It works when I’m editing in Elementor, but when the section is live, the controls do not work. I’m at a loss. I checked the console and this error appears:

Uncaught TypeError: e.indexOf is not a function
    at S.fn.load (jquery.min.js:2:85076)
