Our Scrum board is configured to display sub-tasks. The filter displays the sub-task and there is even a single sub-task that displays on the board. However, all but that one lone sub-task are not displaying. In addition, the sub-task will flash on the board right when it loads, and then they will disappear.
All projects are using the same workflow, privileges, and have the same statuses as the sub-task that is currently displaying on the board.
