Ahhhh...you know, sometimes when you change from one panel memory to another, the settings will change also, especially when the mode is set to expand. If this is the case, switch to normal and try again. If none of the settings move or change as you work through the panel memories, but the apc moves, then I would guess you have a problem that won't be easily solved. Your tech rep should be able to give you help on this, also. He can be reached via your dealer.
