I am finding that quite a few of the to-do's I create disappear from the dashboard & then reappear IF I randomly access the ticket that I created the task/to-do from. If I don't access the ticket that I created the todo in it won't show up on the dashboard.  Some of my tasks do show up so it is never clear why some are there and some disappear. 

I am missing a lot of important tasks
