navigationBarItems does not work as soon as position changed

Dear experts.

As part of NavigationView there were added navigationBarItems. The button defined in the following way.

 }.font(Font.custom("Muli",size:18)).background(Image("Header"), alignment: .center).navigationBarTitle("News",displayMode: .large)                .navigationBarItems(trailing:
                    Button(action: {
                        if self.newArticles{
                            self.newArticles = false
                            let realm = try! Realm()
                            try! realm.write {
                                let articles = realm.objects(Article.self)
                                articles.setValue(true, forKey: "read")
                                var index = 0
                                for article in self.articleS {
                                    article.read = true
                                    self.articleS.insert(article, at:index)
                                    index = index + 1
                                }
                            }
                        }
                    }){
                        Text("Mark all as read").lineLimit(2).font(Font.custom("Muli",size:13))
                    }.buttonStyle(GradientButtonStyle())

This works as expected (meaning it is triggering action on click) but as soon as I change position of a navigationBarItem - the button stop working.

struct GradientButtonStyle: ButtonStyle {
    func makeBody(configuration: Self.Configuration) -> some View {
        configuration.label
            .frame(width: 105, height: 32, alignment: .center)
            .foregroundColor(Color(UIColor.init(hexString: "#2D5AD6")))
            .padding(.horizontal,5)
            .background(Color(.white))
            .cornerRadius(15.0)
            .position(x:50,y:65)
    }
}

Do you have a workaround how to make it working?
