Jira v8.5.5
When I add the Jira Issues Calendar gadget to a dashboard and configure it to display Due date, blocks are correctly displayed on the calendar to indicate issues that have their due date set to that date.
However, when I select some other date type from the configuration drop down list, for example, target start or target end date, no blocks are displayed.
I don't see any other error messages.
I didn't find any obvious "known issues" in an online search.
Any ideas how to get this fixed?
