It will not let me manage my realm members

I went to go manage my members but when I tried to all it says is “loading friends and members.” I tried waiting awhile but no matter how long I wait it still won't pop up with anything. I have even tried logging in and out of my account and shutting off my WiFi and turning it back on thinking it was a connection issue but still nothing. I can not kick or ban anyone nor see who is in my realm. I can only add members.
