SwiftUI searchbar not work when change Language

Question

I have the following problem, if I change the language to English, the searchbar still works in German although I automatically translate the texts with LocalizedString.

does anyone have a solution what could be wrong?

Thanks :)

import Foundation

struct Search: View {
    
    let library: Library
    
    @State private var searchText = ""
    
    var body: some View {
        
        NavigationView {
            
            List {
                ForEach(dataVar) { data in
                   SearchViewPresent(library: data)
  
                }
            }.navigationTitle(Text("Entdecke"))
        }
            .searchable(text: $searchText, placement: .navigationBarDrawer(displayMode: .always), prompt: "") {}
    }
    var dataVar: [Library] {
        if searchText.isEmpty {
            return libraryDataMusik
        } else {
            return libraryDataMusik.filter { ($0.title.lowercased().contains(searchText.lowercased())) }
        }
    }
}
struct Search_Previews: PreviewProvider {
    static var previews: some View {
        Group {
            Search(library: libraryDataKlangwelt[0])
                .environment(\.locale, .init(identifier: "en"))
                .preferredColorScheme(.light)
            Search(library: libraryDataKlangwelt[0])
                .preferredColorScheme(.light)
                .environment(\.locale, .init(identifier: "de"))
        }
    }
}

Here is my libraryDataMusik. it's about the fact that the text doesn't work with the searchbar when it's translated to english.

let libraryDataMusik = [ // Section 2 Music
