i already have all my due dates set in jira stories and I need to have a gantt chart to read off of those dates.but gantt chart is not reading the due date of the stories from Jira.

Example: i have story called SS-15405. i set this story start date is 17/07/2018 and due date is 25/08/2018.but the problem is the Big picture gantt chart is showing the start date as 17/08/2018 and but due date is 20/08/2018.
