States of Menu Titles

I'm just learning Storyline 360 and I can't seem to find any information on the navigational states of the menu titles. 

As seen below, only two of my titles navigate correctly where the title is highlighted in blue when the user is on that slide, and then it turns gray once it has been visited. The course did this automatically on two of my slides but not on any of the rest. Can anyone tell me where to go in the course to set it so that it will work on all of my slides?
