We created a hierarchy on JIRA Portfolio with Objective -> Program -> Initiative -> Epic -> Story/Task. The dates on Stories are correct and are being pulled in from the Sprints which populate Target Start and End Dates on Stories. However the dates on the Epic, Initiative, Program and Objective levels are not being populated correctly from the stories. The Target Start Date and Target End Dates are not using the first date for the Target Start Date and last date for the Target End Date from the stories.
