Join Multiple Servers with ONE Client

Whenever I join a server, it ALSO joins the first server in my server list. I can walk around and stuff in the server I intended to join, but the time is set by the other server and I get chat messages from both.

In the attached screenshot, "Desteria" is the server I want to be connected to, which "LegendCraft Hub" is the server I don't want to be connected to.

Deleting the first server in my server ist does not work. If you need a video, I can upload one.

Only log that I got... http://pastebin.com/FdUAbSvp
