Deferred From Virginia Tech

So Virginia Tech early decision announcements came out on Friday and after eagerly waiting for months, I was deferred. It doesn’t make much sense to me, considering several people from my high school with much lower GPA’s and test scores were accepted. I know they say not to compare yourself to other applicants, but I just don’t know why I wasn’t accepted and am completely devastated. Below are my stats. Can someone maybe tell me why exactly I didn’t get offered acceptance and what I can do to improve my chances of getting in Regular decision?

GPA: 3.95
ACT: 29
Intended Major: Political Science
Extra-curriculars: Editor in chief of Yearbook, varsity track and cross country captain, american teen cancer club, feed the need club, key club, etc.
P.S. I am a white female from NOVA
