If the first row of an input is a header (i.e. one that describes the columns below) check has header for that input in the Right pane.
When you first read in a dataset Easy Data Transform will make a guess about whether the first row is a header (it will assume it is a header if it contains no dates or numbers).
If you have unwanted rows that appear before the header, you can remove them using the Ignore field.
You can move 1 or more dataset rows to the header using the Header transform.
