Fastrack operating track wiring help needed

Hi all I need your help.  I wired the fastrack operating track show in this diagram. It works perfectly with the asc2 / legacy remote.  The problem is I would like to use the manual unload button also.  When I press it, it shorts and trips transformer.  Probably because of jumper soldered shown on diagram?  How do I fix this so the unload button also works. I don’t need the magnet to work if that helps just the inside rails.
