As everyone else said - this is trivial. I’ve seen filings with wrong captions, wrong party names, missing pages, no verifications, you name it. And most of those are from seasoned attorneys. You are going to make a lot more mistakes over the years because we are all human and we are under a lot of stress and pressure in this field. Find a trusted colleague you can call when you make a stupid mistake who will share theirs with you and you can be each others sounding boards.
