Story disappears from Unified Backlog when underlying Incident or Task is closed by systemIssue When Unified Backlog is installed you may add a Triage Board to take Tasks in that may then be converted to Stories and added to your Agile Board's Backlog (Unified Backlog). OOB, when the original task (e.g. Incident) is closed, the associated Story record which would be displayed in the Agile Story > Backlog, would be removed. This is expected behavior, as the thought process behind that implementation is that the life cycle of a story created out of triaging a record would be shorter than the lifecycle of the original record.CauseWhile this behavior is OOB, you may wish to modify two OOB Script Includes: 'BacklogMetaDataService' and 'AgileBoardMetaDataCommonUtil' to not hide Stories when their original tasks are no longer active.
