is there something wrong with facebook?

[Femme fatale]

Ok this is weird. A friend of mine added some pictures and she tagged me on it.

I could see the notifications when people commented or liked the photo and when i went to my friends profile i couldnt see it as a friend and it says on top add as friend. i have ask my friend if she have remove me and she said no and she also said that she can see me as a friend?

I check my friends list and i can see her there but when i go to her profile it says add friend? I check the profile of other people and although they are on my friends list some of their profiles says add friend.

Anyone else experianced this? Thanks
