CS Forms: Filter not working

Hi,

I used the example from the YouTube video regarding the filtering of the post but this isn’t working. I am displaying a custom post type archive, which shows up fine. I add the as in the video and connect with the post container ID. I can see the Loading UI but the posts do not filter.

I was using Search and Filter Pro prior and have now deactivated the plugin but still doesn’t work.

Any pointers will be appreciated. Thanks.
