Search Custom Taxonomies within Directory Not Working

I have tried to use two different plugins to search within the custom taxonomies I'm using in the directory plugin and both keep returning "No Results Found".

I have tried to use "Geo My WP" and "Advanced Custom Post Search".

Could someone please take a look for me? The search and results page is: https://aaie.net/consultant-finder-new/

The custom taxonomies (created with custompress) are Crop Expertise and County Served.

I have ran a plugin conflict and theme conflict test and the issues is still occurring. Support access is granted.

Thanks,
William
