Lab 2b

Well, it would help a lot if you included a screencap so i could see what's going on. My guess is that you're looking at the Recently Viewed listview which would only be showing you those three even though the others are there. It's just you didn't view the others yet so they don't show up as Recently Viewed. You can click the downarrow on Recently Viewed to select All and it will show all of them, including the newly imported ones.

Anyway, just read and follow every instruction and it will tell you exactly what to do.
