The list of labs in JHS is a bit tricky to understand. The name you see is not the name of the file but the name of the lab you see in the beginning of the file. Open a lab and you see what is there. It is a great tool to use as a teaching tool and so easy to work with. Just change the contents of a file and you have a new lab.
