@alexandrud I found a minor issue with WFC on my system, Win10x64 v2004. It won't show invalid rules after selecting show duplicate rules in the rules panel. If I select show invalid rules first in the rules panel then they show, but if I select show duplicate rules first and then select show invalid rules then they won't. I have to select refresh list and then select show invalid rules in order for them to show. Like I said it's minor, but I thought I would bring it up here in case you were unaware of it and would like to change the behavior so that it always shows invalid rules whenever invalid rules is selected, assuming you can reproduce it.
