'My Tasks' view appears differently to others



In ‘My Tasks’ I arrange all my tasks into order manually (dragging them into place), and separate then using Sections. When my colleagues look at My Tasks, the tasks go in a random order and there are no section headers. Selecting ‘Save as Default View for Everyone’ does nothing.
Most or all of them have a ‘Carl’s Tasks’ tag to put them into a project… My Projects does the same thing. All out of order, no section headers.
