I have a problem in my account – Foursquare Swarm: Check-in App Review

I have a problem in my account when I unfriend some of my friends I still can see their check in even if I block them and also I cannot see some of my friends check in I don’t know what’s the problem I try to logout and to delete the app to see if maybe the problem will be fixed but unfortunately still the same And if someone wrote for me a comment on my check in it doesn’t appear to me I have to go back to my check and to see if someone Wrote for me or not
