There may be a translation differences here. In English, the other dropdowns say "Any", meaning any value will be considered a match. The idea was that, if you selected specific values, those would be listed, otherwise any value would be considered a match, hence the wording. Saying "None" makes sense if we think of it as "No filter is selected", but it doesn't really make sense in the context of "None will be matched". Having said that, I'm not opposed to changing all fields to say None if nothing is selected or All if all are selected. I'm curious what people think is the most intuitive wording though. My own personal opinion is that I think I prefer "Any" when nothing is selected and "All" when all values are selected, but I don't know if that's confusing to some people, as I think some people may expect to see something more like "None", meaning nothing is selected.
