It's not that bad, I had a friend who did the same and still got into chicago, but you always wanna be on the safe side Even though ETS is telling you that the schools received them, I believe it takes about a week. Just contact admissions, and don't worry about it. To be honest, uploading the score report is just as fine, but, again, to ease your mind call up admissions tomorrow and kindly explain the situation.
Are you able to see the status - whether or not the school received the report - through the application website, it's usually like a self-tracking page that lets you see what they've received and what they haven't.
