I have implemented Incremental refresh on a Power BI report by using Parameterized Filtering on dates, after publishing the report it get refreshed fine first time but when ever I am trying refresh it again its showing me following duplication error with different tables, even though  there no duplication present in Actual tables. This is the error I get: 

Column '<"Column Name">' in Table '>"Table Name">' contains a duplicate value '<Value>' and this is not allowed for columns on the one side of a many-to-one relationship or for columns that are used as the primary key of a table.

can someone help me out.
