As @Slytherin21 says you are not allowed to apply to both ED to Cornell AND REA to Georgetown. You may have figured this out by now but if you did not you need to change one of your applications to Regular Decision immediately as both schools will be releasing their decisions very soon. Not only is it the ethical thing to do, but if either school sees that you violated its policy they can rescind your offer. Based on the details of your post, they will be able to most likely figure out which is your application. I’m sure it was an honest mistake. Good luck!
