Hi,
In my timeline I have several Epics, all of them have child tasks, but some of the epics do not show the foldout icon and the progress bar, see attached image, the topmost epic is selected and shows tasks on the right. Any idea why the foldout and progress is not visible?

Note: Strangely new tasks will show up under the epic in the timeline view, then also the progress is back again, but only for that new task. See below, on the right the complete amount of progress (90%) on the left, only showing one task and 0% progress?
