Request URI too long

Hello, I’ve used the free plugin to create an options block and set some conditional logic. I have the block appear for all products in this category, and I’m setting conditional logic to show on specific variations. When I type in to the Display Rules box, it will show me a list of variations. I’m finding that’s working pretty well on a new site I’m setting up. However, after adding more products to the site, this has stopped working. Now it just searches and never gets an answer. I see it makes a GET request in my browser to a URL like: https://website.com/wp-admin/admin-ajax.php?term=TESTING&action=woocommerce_json_search_products_and_variations&security=TESTING&post_type=product&limit=30&include%5B%5D=2908&include%5B%5D=2909&include%5B%5D=2910&include%5B%5D=2911&include%5B%5D=2912&… ; But it’s a REALLY long URL, with the ‘include’ repeated over and over again. And the server gives an error about long URLs, so it just won’t work (error code 414). It seems like this should be a POST request, not a GET request with such a long URL. Is there an option or workaround for this?
