Hi there Roberto,
Thanks for reaching out to us on this! Unfortunately FilterBar is not compatible with full view shortcodes yet. We have an internal feature request for this, and I’ll add your thread to it. There’s still not set date for when this will be ready, but when it’s done we will post an update to this thread to let you know about it.
For now the only way to have filter + calendar is to use the default events page.
Please let me know if there’s anything else I can help you with,
Best,
Nico
