I set up a task to repeat every 2 weeks on a certain day of the week. But the first time I completed the task and marked it complete, it was completed like any other task, but no new occurrence was created for 2 weeks from now. 

How can I actually set up a repeating task that actually shows up as scheduled for each date in the time period designated, and where I can complete the task on each date but still have it for all future dates?
