2 Questions regarding Chat Addon and Loot Window

[RandomGuy]

Hello everyone,

So i have 2 questions regarding this interface. The first question is about the Chat.
This confuses me quite a bit. On 2-3 Chars i have two Chat windows in the bottom left and in the bottom
right. But on the other characters its perfectly fine and there is only one windows on the left. I've had this with chatter already and with the new update.



So how can I set up like it is on the other characters with only one window?

My second question is how can I get the /Loot window to show up automatically? Am I missing something?

Thanks in advance.
