When you create an ad-hoc task for yourself, it's added as a task to your personal project. However, when you go to that personal project, you cannot see your personal tasks unless you create a special filter to see them.
The logic behind this is faulty because this is a task that I created and is priority for me to work on. So having it not show up, doesn't make sense.
My recommendation is to un-hide those tasks so they display when you use the "All" task filter.
