Combined calendars wont load

Hello,

I’ve updated from the GCal events plugin and love the new look thanks.

The individual calendars load perfectly.

My only problem is that I can’t get a combined calendar to load. It just displays a blank gap where the calendar used to be. Any idea what I should be looking for to fix this problem?

Thanks,
Emily
