When you have a Jira Calendar which shows versions, it displays the error Jira Calendar Test truncated to show only 1,000 issues events even if you have less than 1,000 versions. The limitation should check only the items displayed in the Calendar and not only issues.

Repro steps:

1. In a Jira project create a few versions in the same month.
2. Generate over 1,000 issues for that project in the same month
3. In Confluence, add a Jira Calendar and show only Version Due Date.

Even if there are less than 1,000 versions, Team Calendars display the error message.
