I dont know where to post this so if this is the wrong place maybe someone can either help or point me in the right direction.

I have at least one person who does not show up on my FB account if viewed on either my pre or my TP. If I views on my pc or android I can see them.

not only can I not look them up in friends list, but I also cant see there posts( either status updates or if they post on my wall or comment on my status or messages sent directly to me).
