在區域設置上連續設置標籤文本時發出

Question

在我的JavaFX應用程序中，用戶可以選擇英語或印地語進行顯示。如果我不斷地在英語和印地語之間切換，在一個階段，印地語文本中的空格或特殊字符會被一些水平線替換，如截圖所示。 我已經嘗試在單獨的線程中設置標籤文本，但沒有用。 是否由於緩存問題？我試圖在設置之前清除標籤文本，但仍面臨同樣的問題。此外，標籤的緩存屬性被禁用。有什麼建議麼？

我指的是博客[Link] [1]中的'I18N實用程序類'。只要用戶選擇了語言，此類就設置語言環境，並觸發標籤的textproperty()。

這裏是代碼片段：

public class example implements Initializable { 
    @FXML 
    private Label dateLbl; 

    public void initialize(URL url, ResourceBundle rb) { 
      engBtn.setOnAction((evt) -> switchLanguage(Locale.ENGLISH)); 
      hnBtn.setOnAction((evt) -> switchLanguage(new Locale("hi","IN"))); 
      dateLbl.textProperty().bind(createStringBinding(() -> 
       I18N.changeDate())); //DATE LABEL WHICH IS SHOWING WEIRD BEHAVIOUR 
    } 

    private void switchLanguage(Locale locale) { 
     I18N.setLocale(locale); 
    }
