Fortx--dd did the same thing. When she went into the application page, all the info was already filled in based on her SS application.
As an aside, we did notice that they had one of her ACT scores wrong on the application page, and she tried to update it, but it said her info has already been processed by USAFA and it can only be updated by contacting USAFA admissions. Her summer seminar app shows the correct scores, so it must have just been a clerical input error on thier part. (they gave her 3 extra points on the math ACT, so she'd rather keep the mistake, LOL, but alas, she will call her counselor this week to correct it)
