Notice how the track selection of that channel changes in the Mixer window. You can change the routing by dragging up or down. This shows which insert track the channel is routed to. This will open up the Channel Settings window for that track and in the top right-hand corner you'll see a box labeled FX. To see what track a channel is routed to, first select the track by clicking on it in the Step Sequencer window.
