I have a handful of tasks (5-6) that reappear every day in my "Planned" view when I open To Do in my browser. I have to mark them all as "completed" every day to get them to go away. They aren't tasks that are set to "repeat," so I'm not sure why this is happening. They show up as "earlier" because the deadline for them was months ago, which is also when I first marked them as complete. I rely on the browser version because my work admin does not allow the software to be downloaded.
