Thanks for instant response. Yes, this is the only way to save all the jobs done I guess. But I just initiated a new one...the old one is still there and I cannot delete any of them...has no idea to start a new one for myself (it's said one account can submit for family members up to 5, it is!)
I noticed before I finally submitted an existing application, I cannot initiate another one for the same purpose. But right now, I can see and edit my old application, and looks OK if I resubmit it except I cannot change the calculation period update, which Jeff just mentioned his way to solve the problem.
Headache, anyone has the experience about this? Start a new one or keep the old one with an explanation letter?
