Visual Studio 2019, Kendo 2020.1.219, Net Core 3.1

I am trying to use a tag template to display the number of items selected rather that displaying the selected items. The multiselect gets the data correctly but when I select an item in the list I get an error saying 'values' is undefined. If I remove values it says maxTotal is undefined. Any idea what I am doing wrong or missing?

    @(Html.Kendo().MultiSelect()
        .Name("SBN")
        .DataTextField("Text")
        .DataValueField("Value")
        .Placeholder("Select SBN...")
        .TagTemplateId("SBNTagTemplate")
        .TagMode(MultiSelectTagMode.Multiple)
        .AutoClose(false)
        .DataSource(source =>
        {
            source.Read(read =>
            {
                read.Action("SBNMultiSelect_Read", "Report");
            })
            .ServerFiltering(true);
        })
    )

<script id="SBNTagTemplate" type="text/x-kendo-template">
    #:values.length# out of #:maxTotal#
</script>

Hello Richard,

Thank you for the shared code snippets.

I was able to render the template correctly by switching the tagMode to single. Attached you will find a small project for reference.

Let me know if that would resolve the issue.
