You're doing some very unnecessary things.
Firstly, remove all those 'bottom' events you have set up in front of the other events (the items); those are useless. The player does not need to always stand on an event to activate it. Simply set those items as 'same as character', then you can activate it just by standing next to it and pressing the action button.
Secondly, turning on a self switch, which switches to a page that ... turns on another switch, is pretty redundant too. Why are you not turning that switch on instead of the self switch?
