CSV Headers Do Not Match and Something wrong with Headers or Columns

I have tried uploading many different variations of our predictions, but whenever I upload city, year, weekofyear, and total_cases, an error comes up saying that they expected ,total_cases and not ,weekofyear, totalcases. However, whenever I try to just upload the same file but with just total_cases, an error comes up saying “Oops! Looks like something’s wrong with the headers or columns of your submission.” If anyone else figured out how to solve this problem, please let me know. I would be super appreciative.
