Certification help

its saying that i have not done the roman numeral converter but i have, and not only that it shows it as completed in my free code camp logs… i was wondering how to get this fixed so i could have that beautiful beautiful certification i have been working so hard at. also let me just say… this is hands down the most amazing site ive ever used. Im actually mad there are not more places like this around (not even the free part, its the amount you guys have and the way you do the lessons, way better than learn by vid).
