Won't let me submit art supplement

<p>I had originally applied ED for one school but got deferred. I submitted the art supplement and my application and later added other schools to my "my colleges" list. Now whenever I go to the supplements section of another page, it says "see your submitted arts supplement." I don't want to see what I already submitted, I want the ability to submit it again to new schools. Why won't it let me?</p>
