Hey @Josh,
We unfortunately can’t help with code customizations or modifications and such. Please read more here ? https://theeventscalendar.com/knowledgebase/what-support-is-provided-for-license-holders/
As a bit of advice, to try and help a bit, I would recommend maybe playing around with PHP’s $_GET super-global. Not familiar with this? Well, while you can Google around for more details on it, one thing it provides is often some information about the current URI.
I would recommend adding code like this just for testing and tinkering purposes:
var_dump( $_GET );
Add that somewhere in the header of your site, then go to different URLs. You should see different values returned for different pages, based on the URL.
You can hopefully then use that to selectively show things on only certain category pages and not others, etc.
Something more WordPress-specific might be to do a similar sort of checking-and-testing, but with the global WP_Query. How to do that? Well, again, throw a var_dump() into your site header to see how it works and tinker—something like this:
global $wp_query;
print_r( $wp_query );
I hope these tips help you filter and selectively display your customizations.
Cheers!
George
