Filtering makes the total time disappear

Hi @Julien_RENAUD, thanks for posting. Unfortunately, this is considered an expected behavior for now, but I’ve already noted this feedback for our Product team. For context, the rollup is purely visual and only available in the List view, which means that the automatically calculated value that you will see in the parent task in List view will not be visible in any other view. This includes the task pane, the cards in board view, and the filtered versions of the list view. We are also tracking this feature request here.
