Unable to update any date field on Team Calendar using JIRA Issue Date event type

Setting up a 'JIRA Issue Dates' event on Team Calendars and choosing a data range including the 'Issue Created Date', while "resizing" and/or drag-and-dropping any issue on the calendar (which basically updates/changes the selected days on this issue) returns a JIRA permission error on the screen.

Steps to reproduce:

1. Have issues on JIRA
2. Create a calendar on Confluence (or add it to an existing one)
3. Add a 'JIRA Issues Date' event type showing a date range using the 'Created Date'
4. Resize the end of the issue/Update the due date of the event
