Hi Billy,
Thank you very much for the details, it helps us a lot!
One major issue I see here is that you are using some sort of a custom Elementor widget. I am not sure of the name, something like Courses archive or similar.
The plugin is designed to work with the Posts and the Product widgets for live results filtering. Switching to the posts widget should resolve this issue. Other widgets may work, but it is a gamble, it highly depends on how they are programmed. Unfortunately there are thousands of different widgets available, they are changing daily, so we can only guarantee the core posts and products widgets compatibility.
