NetworkManager.DisconnectClient() is disconnecting both Client and Host. #3019

Description

I’m trying to implement a function to Kick a player out of the Server, but upon adding this function to a button event:

NetworkManager.Singleton.DisconnectClient(1, "Kicked by LobbyHost.");

Logs For Client Disconnect:

Logs For Host Disconnect which happens after the Client Disconnects above:

It kicks BOTH the Client with ID 1 and the Host with ID 0.

Reproduce Steps

Implement a button with the following:

playerSelectable.kickMemberButton.onClick.AddListener(() => 
                        {
                            NetworkManager.Singleton.DisconnectClient(1, "Lobby Mananger kicked.");
                        });

Actual Outcome

It should only disconnect the specified ClientID.

Expected Outcome

Upon calling NetworkManager.DisconnectClient(); it should only disconnect the specified ClientID and not the host. OR indicate what is causing the Host to disconnect. I'm still trying to figure what exactly is configured incorrectly that is causing this issue. Advice/assistance appreciated!
