WHAT Should I do?I found out a mistake right after I turned in my common app essay

So I turned in my application. And right after that, I found the first paragraph of my essay that I turned in was a line of messy code like “???”, which I have no clue why it happened. I assume it might be computer error. My original first paragraph has two lines of normal sentences, which is pretty short. Other parts of my essay are fine. But it is still weird for a college application essay to start with a line of messy code like “???”. Is this going to influence me a lot? And is there any way to fix it? I emailed the admission office of the university, but they are too busy so they send an automatic reply to me. I am not sure if they really saw the problem I told them.
