A lot of filters are missing the “null” or “blank” option to filter by. There are a couple of ideas you can upvote.

Thanks, it was one of those things where I kept looking because I thought “there is no way this isn’t a standard feature for rule filters”. I upvoted both of those.

I agree, seems like something that should have been there from the beginning.
