I had just completed dealing with starred tasks, and and had unstarred each task, then I clicked on the "Starred" tab, and I get the message "9 active tasks are hidden due to your filter settings. Turn off filters", and so I clicked on "Turn off filters", but I still see the same message and not active tasks.
Am I doing something wrong? Do I misunderstand how this should work? Is this a bug?
This is a bug that we hope to fix in a future update. What happens is that if you edit a bunch of tasks, the counter that keeps track of the number of tasks inside each tab can get a little off. If the counter is off, it will sometimes say that there are tasks that are hidden, when there really aren't.
Any time this happens, you can simply reload the webpage to make it recount, which instantly fixes the problem.
