Next-gen board trying to create a 5th column

Edmond Melkomian_d8mrp1

I am in a next-gen board, I was able to create a 4th column (todo, in-progress, done AND escalated). 

But now I am trying to create a 5th column (in-active) for cases that are inactive or we decided to put off for now. 

I can't find a way to add a 5th column. 

Does anyone know what I am doing wrong? Can you suggest something?

You should add it the same way you did the fourth column.  Could you explain what you are doing differently for the fifth?
