Been having the same problem and have tried all the settings possible. Seams that the digital read out is the only thing wrong as the graft is right. Seams to happen when I get a second return on hard bottom and the digital reads the second return. I suspect that the adjustments don't help as I think the data for the digital read out and recordings for Auto Chart Live is used before the setting take effect. HB CS doesn't know how that works but they know they have a problem. Let's hope for a fix. Don
