Two Views When Adding Resource or Activity

I taught a class last night to some of my newbie teachers.  We reached a point of confusion when I was instructing them on how to add a resource or activity.  My view, which was being projected, shows two separate options as shown in figure A below.  Their screens were showing one option as shown in figure B below.  We're using the same server, same browser, same class, etc, etc.  I can't, for the life of me, figure out how to change my view to match theirs.
