In my settings i have Trade disable, and not enabled, yet its showing up in my bar of chats, it might be a glitch, but i refreshed teh page, and went to another page, and it still persists.

Figured out if you Enable, then Re-disable the chat it goes away, but still, it is a bug that is happening :P
Just realized, every time you refresh, said problem resets, never mind XD
