Pivot Values only accepting single column

PLEASE FILL OUT THE TEMPLATE

**Describe the bug**
when using Pivot under Reshaper, I am unable to drag and drop two columns into values section. Only way i am able to get the view i am looking for is by going to kwargs and creating a list of the two fields i want to sum by

For example my table includes product line, item number, revenue, and units. I want to summarize this by product line
