You may have noticed that when you make a callout a stair, the arrow doesn't show in the view.
This is part of the new Component Stairs functionality. If you want to add the stair arrow and text in a new view you will need to go to Ribbon-Annotate-Symbol-Stair Path and then click on the stair in question.
Visibility Graphics-Annotation Categories-Stair Paths controls the Stair Arrow and text visibility (this is true for the Component and Sketch Stairs). The arrow is now a System Family and can be adjusted.
The Stair by Sketch retains the 'old' integrated arrow and text graphics.
