To help clarify things.
“Active Tasks” only shows the “jobs” that are to be performed, not every detail of that job as that would take up a lot of room about the “overall” task being completed.
Active Snapin Tasks, is where you can see the individual tasks, the host it’s working from, and their current progress states. Of course they only show up when they’re in pending/progress states. When they’re completed they’re no longer considered active.
This is NOT a report of tasks, but rather an “overview”.
Report pages work differently, in that they should display completed items. Though I’ll admit it’s been a bit since I looked it over.
