Hey, thanks for all your replies.
Well.... I happened to be fiddling with the Stomp Mode Switch setting, while at the same time turning the Preset Mode Switch setting and all of a sudden "10 Switches" appeared. When I tried to turn it back, it doesn't return to 8 Switches. It does eventually, if I am turning the Preset Mode Switch back and forth through all it's possible settings. It's like the Helix needs to have something changing in the 2nd knob, before it will recognize I am turning the third knob. Like I said previously, none of this happens when I am adjusting a value associated with Amps or Stomps. Knob 3 adjusts the values perfectly. So, I can make my screen look like your screen capture, with a bunch of simultaneous knob turning.
Can't help but wonder if others may be using the third knob so rarely they may not even notice that it works inconsistently in Global Settings. At least that's what I observe! After it does change the number of Stomp Mode Switches, I can then set whatever Preset Mode I want with the second knob. I guess that's a work around, but I still see this as an inherent software issue that is not resolved by installing the present firmware or a Factory Reset. I can say that, because I successfully did both today, and still could not get knob 3 to work afterward, until I started turning both the second and third knob at the same time. Tried the same trick in the other Global menus and could get the third knob to work in them, but it's incredibly uncontrolled movement across settings that offer a range of values, and can even move in the reverse direction that I'm turning the actual knob. Specifically, on the Ins/Outs setting for Mic In Gain! It doesn't seem to behave like that in the other Global Settings. If it was a physical or electrical problem between knob 2 and knob 3 on my Helix, you'd expect to observe the same wacky behaviour when adjusting Amp/Stomp values. Never even noticed this issue, until I bought a Helix preset that used 10 switches...
Anyway, that's the poor workaround I have figured out to date, and would welcome other comments as to whether I am the only one observing this issue? Right now, we've only got a verified sample of two... where I am observing this issue and datacommando is not.
Thanks in advance for any and all feedback
