I have 4 calendars in an accordion Layout, all in a tab called diarised events. They show our members what events are booked in out clubroom, quiet room, what jobs they have volunteered for and a final one for All Events
When a user clicks the tab, the first calendar at the top of the accordion is not rendered. If you click on one of the other accordion sections (all the others are rendered) and then go back to the first one - it then renders ok.
