Our sorting has an initial sort column - that's usually the "Name (as in the example screenshot). When you add another column, you see a value of "2" on that column (see Publisher in the example) - so, the UI continues to sort based on Name, then based on the additional column. To sort on Publisher, click on the sort icon on Name and remove it.
