The Inspector - missing button(s)?

I’m not sure if this is a bug or if I’m just missing something.

I’m finally having a chance to go through the tutorial and I’m on Step 5. It says:

I see a Notes icon (piece of paper), a Reference icon (books line up with one leaning?), a Keywords icon (a key), and what looks like a padlock, especially when combined with the information above saying that the far right icon is a padlock. I click on it, however, and find that it isn’t the padlock icon, apparently, it’s the camera icon for Snapshots. Upon really close inspection of what I thought was the padlock button, I can maybe see that it’s a camera. I have no padlock button. Am I just missing something?
