The My Tasks view, when marking a task complete, old “completed” tasks repopulate.
Welcome, @NicBade,
It sounds like your task is set to be a repeating (recurring) task and maybe you don’t want that.
Repeating tasks show this icon:
To stop the repeat, either hover that cell then click the “x” to remove, or open the date dialog and click the repeating icon at the bottom to remove the repeat function.
Thanks,
Larry
