well, I am not that sure about "what "different accounts" means. I have UAE account but the original game pack is in Chinese. is that maybe the source of the problem?
so how to solve this? Create a Chinese account.
if i make another account, will I lose my game save data? Nope. It will be fine.
can I transfer the save data to another account? Yes.
Thank you for your replies. I will give it a try and will return to you.
