How to initial check items

I have a ListBox like this:

            <ejs-listbox id="Schnellnavigation" ejs-for="SelectedValues" allowDragAndDrop="true" dataSource="Model.Items">
                <e-listbox-selectionsettings  mode="Multiple" showCheckbox="true" checkboxPosition="Right"></e-listbox-selectionsettings>

Motel.Items is a List of Items with a text and a value property.
SelectedValues  = new List<string>() { "1", "2" };

When i load the page the checkboxes are not selected:

Whats wrong with my code? How can i select the checkboxes?

I solved this Problem by myself with the ListBoxFieldSettings {Text = "Text", Value="Value"} but when i add a IconCss the selection of the Checkboxes doesnt work again. I think this is a Bug.
