Showing all rather than filtered

I’ve set up Search and Filter with some custom post types and custom fields and I’m using shortcodes to display both filter and results on the same page. The custom fields I’m using appear to be working as I’ve enabled count and can see how many posts are in each field type.

However, when I click on any of these to filter, the results always show all posts.

I noticed that in the browser console, I’m getting an Uncaught TypeError:

Uncaught TypeError: $(…).searchAndFilter is not a function.

I’d be happy to share a URL to the page, filters and results but I’d like to send it privately.
