Check each channel (and query) windows system menu (right click on the switchbar button or left click on the icon in top left of the window) for "[] Track Urls" and unselect it if found.

This will echo any entries that are set to 'track'.
//var %i = $ini($mircini,tracking,0) | while %i { echo -a Tracking: $ini($mircini,tracking,$v1) | dec %i }
