I'm trying to automate in postman and there's one issue I'm struggling with...

Suppose csv file has duplicate column as below

C,A,A,A
x,1,4,7
y,3,5,8
z,3,6,9

Now when I'm trying to upload my csv file to run the collection in preview of data (before run collection) or while printing the pm.iterationData only the first and last column are there , 2nd and 3rd columns are removed as they were the duplicates of 4th column.
