Error while adding default Row/Column in PivotTableUI

[arnabneogi86]

Hi, When I put rows and cols as default values, in PivotTableUI, those in the UI, cannot be modified. This means I cannot add any more rows or remove any rows in the UI. The error it throws as follows: Warning: Failed prop type: The prop attrValues is marked as required in DraggableAttribute, but its value is undefined. at DraggableAttribute (http://localhost:3000/static/js/2.chunk.js:336459:5)

Kindly let me know if this can be fixed or I'm missing anything. I tried to use the example given. Still same error.
