When changing the infill percentage in the Infill tab, the slider above the tabs is updating on edit, but the label next to the slider is not updating until you hit ok and open Edit Process Settings is reopened
Looks like this was in 4.0.0 which was automatically launched for some reason when I launched via spotlight search. Tried in 4.1.0 on the mac that was exhibiting the problem and doesnt seem to be a bug anymore
