So, I click on the setting option given for the Removed Other column in Applied steps:-
After refreshing, i was expecting something like this
But, the output is :-
As you can see that even the country column is also get unpivoted. Though the issue look small, But when you have large number of steps, and later on if somebody want add an additional column in the visualisation, and this issues become very problematic and i need to delete all the steps till the point where i need to add a new column.
Hope in future updates this issue will be resolved.
