Currently, the Gantt Chart displays the parent estimation based on the start and end dates of the children, not on the sum of the duration. Your screenshot shows that the earliest child task starts on 13 Jun 2022 and the latest child task ends on 14 Jun 2022. According to this, the parent task will be displayed between 13 and 14 Jun 2022.
