How do you setup those custom post types "wow-classic/news" and "tbc/news"?
There should not be "/" characters in the post type slug, please check these:
1) Find and edit those two post types "wow-classic/news" and "tbc/news", make sure your are using correct slugs
2) Edit the codes you mentioned above, use the same post type slugs.
Those are the correct slugs, as I mentioned it was working perfectly until the most recent update.
Anyway, I've tried using both "wow-classic-news" and the one that was working until now which is in the rewrite "wow-classic/news" and neither are working. Attached a screenshot.
Please try to output the [wpv-post-type] shortcode directly, test it in frontend, then use the frontend result in the [wpv-conditional] shortcode, and test again
2) In case it is a compatibility problem, please deactivate all other plugins, and switch to WordPress default theme 2021, deactivate all custom PHP/JS code snippets, and test again
Thanks for the details, I have done below modifications in your website:
Edit the problem page: hidden link
Replace the "Fields and Test" block with a shortcode block, copy/paste the same codes into it:
