0 - 1 of 1 tags for dense rank

For every Sale_Month, I would like to get the top 3 Item_Types for each Employee_Name dense ranked based on the on the Num_Sales. Currently I am getting "Modified competition ranking" instead of Dense Ranking"

Dense ranking ("1223" ranking)

Modified competition ranking ("1334" ranking)

 

How can I change my SQL to get "Dense Ranking" instead of "Modified competition ranking"?
