D70 - Editing with Tone Palette Sliders

[qqquartzzz]

I rebuilt my old D70. Fired it up and reloaded the factory settings via Midi.

I find when I'm editing, for example, Tuning, with the Tone Palette Sliders, it seems to "slide" into the value.
Say the value of one of the tones is -12 and I want to make it 0, I use the slider to slide it up from -12 to 0 and as I get closer to 0, it will go up to +2 when I stop sliding. If I try to slide it back down slowly, it will go past 0 and go to -2 or -3. Kind of like it's skidding to a stop, but, sliding over the finish line.

Anyone experience this odd behaviour on their's? My previous build didn't do this.
The editing with the slider was pretty bang-on. I slid it to a value and "bang" that was the value.
All the parts are original factory parts.

Anyone know of a fix?

Thanks.

Re-initialized using "Hold down 8 and turn power on". Tried the sliders and they still "slide" into their values once you stop using the slider. But, if I pinch the actual fader and move it with a little fingertip resistance, I can land on my preferred value a little easier. So I'm going to say that's the fix for now.
Unless someone knows of a firmware update that fixed this little bug.
