How to remove duplicate previews from XCode 12.2?

Question

I'm a beginner in XCode and clicked on duplicate preview twice and now I can't find a way to delete the duplicates. I'm sure this is something pretty simple but I've been searching and trying everything for like an hour and can't find a solution for it...

Can somebody help me?

Already found where the problem was! Every time duplicate preview is clicked, it adds one more view in the code.

The code below shows where my "problem" was:

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        Group {
            ContentView()
            ContentView()
            ContentView()
        }
    }
}

To fix this "problem", simply remove two ContentView() from the code:

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        Group {
            ContentView()
        }
    }
}
