Everyone gets kicked from realms server randomly and constantly by an "operator"

Hi, we seem to keep being kicked from our realms server randomly and constantly since the 1.8 update. It is getting extremely annoying. I am not sure if it is a bug or a hacker but I have no control over this situation as the realms host, even when alone in the server being the only operator this issue still happens. Thank you for your time and I hope that you can save this issue.
