Good evening Tirfari and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about your test event not being visible.
I would love to help you with this topic.
I believe the test event in question is http://igahu.com/event/3060/
I am able to see it on both the list view and the monthly view.
But, to see it on the monthly view, you have to fast forward 1 year in the feature since your event is in December 2017.
Let me know if that helps.
Have a great day!
Geoff B.
