Nullreferece error on sftextbox

Question

Good day! I'm experiencing an error regarding Sftextboxext suggestion Box. The control seems to work well on the first instantiation of the a window.

But when opening it on the 2nd time will cause an error, when the arrow is pressed.

Syncfusion.SfInput.Wpf.dll!Syncfusion.Windows.Controls.Input.SuggestionBox.Listboxitem_Loaded(object sender, System.Windows.RoutedEventArgs e) Unknown

Please help me with this problem. Thanks in advance!
