Using the JIRA Issue/Filter macro to list issues with the Epic Link field, this field is showing the epic's id instead of its title, (it was showing the title before September/29).
- Create an issue on jira and fill the Epic Link field
- Insert a JIRA Issue/Filter macro on a Confluence page and search for that issue
- Under Display Options -> Columns to display add the Epic Link field
- Save the macro and publish the page
In the Epic Link column it should display the Epic Name/link
Currently there is no known workaround for this behavior. A workaround will be added here when available
