I expected to see: Show correct result when "Key Issues" is selected - (try Healthcare Markets).
Instead, I got: It shows result from different Post Type (Post), it didn't show result from CPT (Litigation).
Btw, search for other taxonomy (jurisdiction), custom fields (status, plaintiff) shows the correct result (CPT - Litigation).
-- note --
I'm using views ID 1297 "Global - Litigation" (see screenshots)
I turned on debug mode (in Toolset > Settings > Front-end Content), the results of which you can see in the screenshot.
In the lower part you can see that the query arguments are correctly formed (the post type is "litigation"), but in the upper part the actual SQL query is wrong, the post type is "post".
Something is intervening in creating the query.
I switched from your child theme to twentyseventeen and the problem was resolved.
Your child theme must include some custom code that affects the query, and you'll need to review it. If you can't identify it by eye you will need to comment out blocks of the child theme code at a time and re-test to try and narrow it down that way.
When you have found the offending code if you let me know I may be able to help identify why.
