Add New Calendar does not work for Confluence page

[Deleted user]

I was able to add a team calendar to the Confluence page of one of my teams.  But, trying to do the same thing with another team (exactly the same page structure) when I click on "Add New Calendar" to create a calendar for the team, it just exits the dialog box and dumps me back to the edit screen for the page.  Adding a new page to that team results in the same failure.  But, other team, no problems, I can create calendar after calendar.  What is causing the failure?  (I can provide video if needed.)

This apparently just needed time, and has successfully been added.  Not sure what changed.
