Hi there Liam,
Thanks for getting in touch with us! I can help you here…
Regarding question #1, from a first look I cannot related this behaviour with any known issues (neither see any errors in the JavaScript console). I’d start by Testing for conflicts guide. This way we can see if this is a problem in our plugin or a conflict with the theme or other installed plugins.
On question #2, let me say it’s not possible to push events from the WordPress site to Facebook. You can only import events from Facebook into the WordPress site. Was this what you were trying to achieve?
Please let me know about them,
Best,
Nico
