Yamaha Genos 2 harmonies

[Elvis1977]

Hi. I'm new here. Normally, I find all the information I need by stubbornly exploring all available options I have in front of me or with the help from Google, but now I'm stuck!!! 😱 What happened was, I created my own harmony, saved it, and then I set it to multiple files / backings / arrangements (whatever one wants to call it) I had stored on "Registration Memory". A few days ago, I noticed that it sounded like the harmony had changed. Instead of the harmony I made and stored / attached to various files, it automatically stores whatever harmony is being used at that moment (like, for example, "standard harmony" if I've just turned the keyboard on). Once I press a file / backing I've  made, the harmony I've chosen to that particular file should just be THERE. Simple. What I mean is that if I would create two backings with two different harmonies, I wouldn't have to worry about anything. It would all be set. If I wanted to change the harmony on one file, that particular file would just change, not the other files. Simple. But, now, all files have the same harmony (regardless of  what I've saved). Can you help me, please??? 🙏 I sincerely hope I made myself clear (English is not my first language). Thank you.
