Totally agree - I’ve posted here about this.
Please see this thread, there’s more discussion about this.
In particular IMHO the QC is trying to be too clever if it’s trying to work out whether you want to return to the point at which you paused changing the parameter rather than just return it to where it started; the Helix system works better here, because to restore each parameter to the start point you press in the specific knob that you were using to change that parameter, rather than have a ‘global’ undo function.
