This is a problem with Platinum and save editors if I remember Corey's thread. Basically when you load your save to edit, Instead of editing your 'current' save the editor reads the 'backup' save so whatever changes you make never reflect when you restore your save. Coreycubed will hopeful re-post his temporary solution. What I do in my game is save over both Slot-1 and Slot-2(and even Auto to make sure) after making my changes in pokesav.
