If you press "V" (View) you should be able to trace that port all the way back to your configuration, as in the pic I attached.
Also, the component you show in the second screen capture isn't connected. Thats what the red X's are...
Last thing, whenyou move the yellow ports, if you press F8 as you have it in move, it will rotate 180 degrees, F9 does 90 degrees, but doesn't reverse the label.
