Someone accepted my facebook friend request but it still says add as friend?

[Sally]

I added someone I know in real life on Facebook today, and I got a notification shortly after saying they had accepted the request, but for some reason, when I clicked the notification it took me to their profile where it still gives me the option to add them as a friend? I can see more of their info than I could before and also it gives me the option to 'see friendship' and 'unfriend' the person. They dont show up in chat and I dont understand what's going on... if they deleted me then why can I still have the option of unfriending them? This doesn't make sense to me.

Report your problem to Facebook, it is a Facebook glitch
