I am currently looking at the All Tasks tab of the Main view. At the bottom of the page, it says "2 active tasks are hidden due to your filter settings. Turn off filters". However, if I click "Turn off filters", nothing changes, and it still says 2 tasks are hidden. What am I missing?
Well, nevermind, looks like I got around the issue. Choosing a view other than Main and then going back to Main cleared it up, though I'm still not sure what was going on.
