Hi Sam,
Thanks for using the Events Calendar.
Here on the pre-sales forum, I’m afraid we do not provide technical support. I would ask that you login and take your technical support questions to our premium forums for that plugin and we can help you out there:

Please note if you have a start and end sales date and today is not between those dates the ticket will not show.
Please create your own ticket with that information and we can help you out today.
Thanks
