having problems with FFusME

ok so im working on my first boss (replacing zone eater) im not changing sprites or stats all im changing is the script when i wanted to test it out to see if everything is working fine and when i x out of it (the monster editor thing) and i hit the save button i run ZNES and load Final Fantasy VI (english version i just named if VI) and when i try to fight zone eater he does the same moves he normally does i know im using the right rom cause its the only final fantasy vi i have named final fantasy vi is it cause it version 1.1? or just something with the editor
