Hello,
Please look at the attachment..
Work duration does not roll-up to the header total..
It looks like it happens whenever I insert/add a new header category with subtasks...

Ad the previous poster mentioned, this is expected behavior, the duration is the time between the start and finish of a task. The duration of a summary task will be the difference between the start and finish (Calculated using the appropriate calendar.) The start and finish of a summary task will be the earliest start and the latest finish of any sub task.
In your screen shot, the calculations look correct. The question I would have is why your latest finish date is set to 2015. I suspect that is due to either a very low unit resource assignment, a constraint, or something else strange about the task.
Of course, let me know if I'm missing something...

Ayansane,
there is something strange in your project. I assume the first column is the duration, and the last the "work", right?
But what are "Energize Area A - 10MW" and "Area A Complete"? They show null duration and work, and yet their start and end date are not equal (which does not make sense considering the definition of "duration", which is basically end date minus start date). This is probably what is making Project fail to compute the duration properly.
Also, I assume you've associated a lot of resources to your tasks, since 3 or 4 weeks duration correspond to 243 weeks worth of work. Is that normal? Finally, did you make sure that you did not assign resources to any summary task (you should never do that)?

This is normal. The summary task (what you call the header) will show the duration of the longest subtask. The reason is simple: duration represents... the time it takes to complete a task. Not the amount of work (that would be the "work" field). And unless you put constraints between tasks, nothing says that the tasks cannot be conducted in parallel, so Project just assumes all sub-tasks will be conducted in parallel, and the summary task will therefore show the time it will take to complete all tasks.
If you want to compute the amount of work, use the "work" field. It will add up in the summary task regardless of when the sub-tasks are worked on or how long they take to complete.
