Hey David,
Thanks for reaching out. I unfortunately am not sure we can help much here, for the following two reasons:
1. We do not make this plugin and thus cannot offer any support for it, or answer questions about it: https://wordpress.org/plugins/the-events-calendar-shortcode/. So, for anything related to that plugin, please post those questions to the plugin authors.
2. We cannot help with custom coding. I only mention this because, unfortunately, if you are finding that CSS files are loading in places you don’t want them to, the only way to resolve this is to dive “under the hood” with custom coding and write custom code that prevents the various CSS files from loading where you don’t want.
You can learn more about our support policies on both fronts here by checking out this page → https://theeventscalendar.com/knowledgebase/what-support-is-provided-for-license-holders/
Please check out that page, and let me know if there is something I can try to help with here.
Sincerely,
George
