My standard Projects view (established from my "Remaining Tasks" perspective) shows remaining tasks grouped by folder (client).

I selected a specific folder and was adjusting existing tasks and adding new tasks when I noticed two tasks appear that I'd marked as completed a couple of weeks ago. The tasks still had their done dates, and the text was displayed with a strike-thru line.

I reapplied my perspective, but the two completed tasks were still there.

Changing the view to All tasks and then back to Remaining finally made these two tasks disappear.

I've never seen this before, and I have no idea how to reproduce the problem. But I figured it was worth reporting even if it goes into the "How about that!" stack.
