From my understanding, the issues I created in the List tab will be copied over into the BigPicture tab to create a Gantt chart. If I delete the issues from the List tab, it leaves a residue of where the task used to be, which in turn affects the BigPicture tab where the Gantt chart is displayed (blanks are shown).
Is it possible to delete/modify the BigPicture Gantt Chart based on the new edited List?
