Hi, I updated my son's new helix lt today. I went from the factory 2.30 to 2.60 to 2.80 to 2.81 and I did a backup every time. My son says that he used to have over 100 preset but now there is only 32. Did I do something wrong or did the update change where he finds them? I did the 9 and 10 button restore as well.
