Skyrim hex troubles in hex workshop

Ok so I’ve been trying to hex edit an item into an ancient falmer crown (seeing as its not obtainable), I placed 1234 gold and an ebony helmet in a barrel in whiterun, save it and place it in my USB and extract the savegame.dat through horizon and opened it into hex workshop, for some reason hex workshop is not finding my gold or ebony helmet, does anyone know why this is happening
