I assume you are looking at your tasks in the "MyTasks" area? There are two setting that control what tasks you are seeing:
- in the view options on this page you can select to "Show only current tasks" (or all tasks if NOT checked)
- current tasks are all task from that past that have NOT been completed or NEW tasks that start within the timeperiod from now to the setting in "Server settings".."Task settings and display".."Define current tasks"
