No "Title Attribute" field on Menu page

I am trying to create a menu and want to use glyphicons as described in the Sparkling theme documentation. When I go to my Menu settings, under Menu Structure I have a Navigation Label field but no Title Attribute. The screenshots in the documentation show these two fields next to each other. Does anyone know why I haven’t got it?

Try clicking on screen option top right corner of the menu page and tick the Title Attribute.

Thank you!
