Ah - this old chestnut! Confusingly, the Project Status filter you have shown only applies to the Unassigned Tasks at the top of the screen (i.e. above the line in the filter pane.) The filter options below the line (Roles and Users) are the only ones that apply to the Assigned Tasks, so at this point at least, there is no ability to filter the assigned tasks by project status. Assigned Tasks from Dead projects don't show on our calendar though.....if you're seeing them then perhaps raise a ticket with Support. David Cornwell
