2017 event isn’t showing

Hi,

I just added an event which is taking place on January 4. I can go to the event details as I know the url (https://bloei.info/activiteit/high-tea-kinderkookworkshop/). But the event doesn’t appear in the calendar (https://bloei.info/agenda/)

I can’t select the next month in the calendar or see it pop up in the overview. What am I missing?

Thank you!

Annemarie
