Finally 🙂 I am just find a little "mismatch" in translation, which confuses people.
Title of the sort order duplicated, but results are different. Seems first sort by answers and second one sort by views.
Views counting is not default possibility of the Flarum. It was added with Flarum Simple Discussion Views with additional sort orders.
I cant say how it can be translated more correctly for excluding duplication. No version at all. I am just continue to use it "as is", but, of course, users ask about this.
