Hi, I submitted 2 jobs and couldn't figure out the problem, could you give me some help? The first job is submission ID: 8154199, and the error is "predictions.tsv must have headers: subjectId, laterality, confidence". But I did have headers in first row of the file. I was guessing if it was because I uesd the delimiter as ','. So I submitted another job with delimiter between columns as '\t', The submission ID: 8155837. However I got the error "No duplicated submissions allowed". I don't know where my problem is, can you help me check it? Thanks
