Guys, seeing a pot on a specific amp act weirdly is a fair thing to report.
@My name is mud , one thing you might not have noticed is that Cliff doesn't always acknowledge or respond to every question or report, he doesn't have time to. Sometimes a thing will get mentioned 5 or 6 times and he'll finally respond with "yes, that's already fixed for the next version". This is because all the posts are read, and all the bugs that need fixing are addressed, but reassuring us with a confirmation or an answer is not a necessary part of the process. So rest assured that I'm sure Cliff has seen the issue, and either already fixed it, logged in a list of things to investigate, or decided it's a non-issue.
Everyone else knows there are some knobs that we've been told can't be turned fast without noise and that's just the way it is. They won't be fixed and instead just shouldn't be assigned to modifiers. But there are others that are more important to be able to use with a modifier and do get fixed. I don't think Mud is in the wrong for pointing it out. Although Mud, one thing I do see happening is your way of speaking, perhaps the way you learned English, is a little less formal or polite than some on here would prefer. I think this is why sometime people push back on what you say. Many are also assuming it's that way with this knob, but we'll have to wait and see.
I know from experience some real amps do this too: My Ameg SVT3-PRO has a TUBE GAIN knob that controls the voltage level on a 12AU7 that feeds the MOSFET power section. Turning it up gives the tube ample power and the power section behaves like a solid state amp. Turning it down starves the tube which makes it respond with some of the sag and dynamics of a tube bass amp being pushed. However, they state in the manual and are correct that if you adjust this knob quickly you'll hear weird sounds.
Ultimately, there could just be something weird about the EQ stack on the Herbie that makes it susceptible to generating noise when turned. Not weird as in a bug, weird as in the amp design. If so, it'll likely stay. You best bet is to wait and see what happens on the next firmware release, and if it's still there it's probably inherent to the way the modelling works with that unique circuit.
