Facebook apps that DO have a box available not showing up as having it available in app options?

[cнєиσα :)]

Ok, so I posted this question 5 days ago, but I didn't get any answers...

I have added apps that I've seen other people have added as boxes on their profile, ex. Profile Song, Mood Stones, etc. Therefore, I know they should have the option available to add them as a profile box. I actually used to have Mood Stones added as box then deleted it for space. I tried to add it again a little while ago, and it doesn't have the Box available (add) option, yet I still see it on other people's profiles? Same goes for Profile Song. I know it can be added as a box, but it isn't showing the option for that in the application settings. Anyone have any ideas?
