Unable to load events of <calendar name> after rename

[lab10 collective]

When trying to view Team Calendars as well as in the "Upcoming Events" section of the Dashboard.

Renaming the calendar back to the old name does not resolve the issue.
The error message *always* references the old name of the calendar, regardless of the actual name.

Installing the newest version of Team Calendars did not resolve the issue.
This is a standalone install of Confluence, not connected to Jira.

Callstack:
