Haha… it seems that for some weird reason your website removes the "" because I typed the names of the buttons that I was referring to inside those symbols…. anyway, what I was saying is that when you type a number and then hit the "Ent" button it takes you to that particular preset, right? Then you press "Select" to select it and it works.
However, if you type the number of the preset and then press "Select" without first pressing the "Ent", it tries to load the preset but it doesn't. It stays at whatever preset was selected prior to typing the number. Try it. I am pretty sure it's a bug, unless I am missing something.
