Hi Michal!
Thanks for getting in touch with us about this topic.
I’m not exactly sure I understand the SEO issue you are experiencing. Could you please provide more information about the problem? You can send us screenshots as a reference that will help us identify any issue.
Also, when coming back please share with us your system information by following this guide > https://theeventscalendar.com/knowledgebase/sharing-sys-info/
Do you mean that you don’t have a solution for this problem? And that your plugging don’t support seo needs?
Our plugins don’t have any built-in SEO tools, so you can use a third party plugin like Yoast SEO to optimize your site’s search results. However, if there is something in our plugins that is causing a conflict with SEO, we’d be happy to have a look and see what we can do to help.
Let us know about it.
Thanks,
Victor
