About the list of friends

I have a lot of friends in Lingq, more than 200.
But the time goes ahead, I’ve lost the connection with some friends and I would like to unfollow them.
At the same time I would like to add some new friends who like my lessons and whom I could help with the language study.
However, last month I can’t update my list of friends. I press ‘unfollow’ to some of them, but they don’t disappear from my list of friends!..
And I press ‘follow’ to some new friends, but they don’t appear in my list of friends!
How to solve this problem?
