Queries - Duplicate Columns After Merging

So I am wondering about something that happens inconsistently when transforming data in Query Editor.

 

I will duplicate a column to apply a transformation (extract, date, multiply, etc.), and when the step is added, sometimes the duplicated column will be deleted, and other times not.

 

Anyone know why this happens?  I have not been able to find anything talking about this.  Thanks!

    Hi RodgerB ,

     

    Need more information, could it be something like "merge queries" and "merge queries as new"?

     

    Best Regards,

    Jay

      No problem.  So, I will duplicate a column in Query Editor/PowerQuery to do things such as extract text from the column, change the date to a year value, or even multiply a column by a value.  When the step is added, the new column will be created, but the column it was created from is still there.  Other times, when I do this, the new column is created, and the old column is replaced with the new transformation.

      It seems very random, so when I'm showing this to someone, I get this question a lot.  "Why is your column gone, but mine is still here?"  I hope this better explains what I mean.  Thanks again!
