Hi Jose, 🙂
Thank you for bringing this issue to our attention. This article from The Events Calendar might catch your attention:
https://theeventscalendar.com/knowledgebase/k/can-you-have-multiple-calendars/
Maybe these topics will help you to solve your issue as they seem to answer the same concern:
However, please note that apart from The Events Calendar, the other plugins mentionned in the topics listed above are not integrated with our theme and might require some custom work to make them fit perfectly.
As this issue is related with the customization of a third party plugin, not with the use of your theme, we invite you to ask for more help from the plugin authors and post your request on their support forums:
https://support.theeventscalendar.com/
As theme authors, the installation, setting or debugging of third party plugins isn’t part of the support we will provide.
We remain available for all support requests related with the use of your theme.
Regards,
