thanks to SolidSnake11 and V2ditata, the possible reasoning for this is actually the DNAS cheat file. if not all codes are in there it will cause this. another tip is if using a PCSX2 emulator, you need to delete the master code in it. if using an actual PS2 you need to keep the master code in there.
