Go back to the build and pull down the "screenshot" selection from the "views" menu and refresh that. That fixes that earlier rack problem. As for the "what goes here" issue, how about this: https://www.modulargrid.net/e/bastl-instruments-hendrikson-- This lets you add a stompbox or three to the build, meaning that you can add more complexity via reverb, delay, chorus, et al pedals. Move the Ciao! to the right end of the skiff, then put the Hendrickson before that.
This is always a useful move when doing skiff builds. 4 or 5 hp can equal MANY hp by shunting the signal off to external devices.
