Deduplication in Power Query can be finely controlled. You can choose which columns should be included in the decision.  By default (in my opinion a bad default)  only the currently selected column is used for the deduplication.  You can modify the Power Query code to include all the columns that are important for your scenario. 

Could you please show on screen?

Let's assume you have this table

You can deduplicate the entire table or you can deduplicate groups of individual columns.
