Custom date field - trouble selecting the correct date

I've been using and loving the custom date field but have run into a wall getting Hazel to select the correct date on a bank statement. No matter what date I point Hazel to in the statement (1st from top, 2nd from top, etc.) the wrong date is being selected. Any ideas how to use this feature in this case so I can get the correct desired date in the file name? Thanks in advance-
