I just ran another test with the pid index-enable disconnected for that axis, and the halscope trace looks exactly the same as it does when it is connected. Is there something wrong with that pin in the pid component or is this a symptom of my ordering problem?

I did another screen shot with the position-cmd zoomed in as much as I could and keep it on the screen. It seems that the index enable falls, and the encoder position is reset,then the PID gets whacked for one servo period, then the position-cmd is reset. I have the PID index-enable pin connected, but I not sure it is actually doing anything.
