I need to work out a fix for this, there are 2 Matt Duffys now. This will need to be re-worked on our end to know which is which from DK's CSV file. I should have a fix in place later tonight. For now, you would need to open the CSV and replace Duffy with his correct DK player ID, which I am listing here:
(7 games ) : 6408910
(12 games all day) : 6472157
