When attempting to display a Team Calendar in a deck of cards the Team Calendar is not displayed if the deck of cards does not have the Calendar on the first card that is to be displayed. Attempting to interact with the calendar refreshes and the Calendar information will be displayed.

Contacted the Deck of Cards plugin vendor for resolution and the reported: "After much investigation, we found the Team Calendar does not show up in

and

macros from Navitabs Plugin by bitvoodoo too. Other than that, from our findings Google Calendar macro is displaying fine in any cards of deck.
Thus, we suspect the issue comes from Team Calendar Plugin itself, which is not compatible in tabs. Perhaps you may get proper assistance from its developers here: https://marketplace.atlassian.com/plugins/com.atlassian.confluence.extra.team-calendars#support"

Please investigate and provide a resolution.
