Problem with loading filter setting on Date columns

So I have an MVC grid where I'm saving the grid settings to localstorage so that I can load the filters and the current page back to the same spot when navigating back from another action. It all works great for almost all of the columns, except for the date column (LastUpdatedDate below). The date entered is there, but you must click the Filter button again on this column to apply it, where on other columns, the filter is applied already on load. Any ideas? Page code below.

@{
    ViewBag.Title = "Vendors";
}
<h2>Vendors Index</h2>

@(Html.Kendo().Grid<VendorRegistry.Models.Vendor>()
      .Name("grid")
      .Columns(columns =>
      {
          //Excel like filtering on columns. Pulls from datasource because default shows them not in order. See Expired for default without datasource.
          columns.Bound(c => c.CompanyName).Filterable(ftb => ftb.Multi(true).Search(true).DataSource(ds => ds.Read(r => r.Action("GetCompanies", "VendorGrid"))));
          columns.Bound(c => c.Address1).Filterable(ftb => ftb.Multi(true).Search(true).DataSource(ds => ds.Read(r => r.Action("GetAddresses", "VendorGrid"))));
          columns.Bound(c => c.City).Width(110).Filterable(ftb => ftb.Multi(true).Search(true).DataSource(ds => ds.Read(r => r.Action("GetCities", "VendorGrid"))));
          columns.Bound(c => c.LastUpdatedDate);
          columns.Bound(c => c.Expired).Filterable(ftb => ftb.Multi(true));
          columns.Bound(c => c.Vetted).Filterable(ftb => ftb.Multi(true));
          columns.Template(@<text></text>)
            .ClientTemplate("<a class='k-button k-button-icontext' href='Vendors/Edit/#= ID#'><span class='k-icon k-edit'></span>Edit</a>" +
                            "<a class='k-button k-button-icontext k-grid-delete' href='Vendors/Delete/#= ID#'><span class='k-icon k-delete'></span>Delete</a>" +
                            "<a class='k-button k-button-icontext' href='Vendors/Details/#= ID#'>Details</a>")
            .Title("")
            .Width(240);
      })
      .ToolBar(tools => tools.Excel())
      .Excel(excel => excel
          .AllPages(true)
      )
      .Pageable(pager => pager
          .PageSizes(new[] { 10, 20, 30, 50, 100 }) // Default page sizes are 5, 10 and 20
      )
      .Sortable(sortable => {
          sortable.SortMode(GridSortMode.SingleColumn);
      })
      .Filterable()
      .Events(e => e.DataBound("grid_dataBound"))
      .DataSource(dataSource => dataSource
          .Ajax()
          .ServerOperation(false)
          .Model(model => model.Id(p => p.ID))
          .Read(read => read.Action("Vendors_Read", "VendorGrid"))
          .Destroy(destroy => destroy.Action("Vendors_Destroy", "VendorGrid"))
          .Sort(sort => { sort.Add(vendor => vendor.CompanyName); })
      )
      
)

@section Scripts {
    <script>
        $(document).ready(function () {
            //Load grid settings from localstorage
            var grid = $("#grid").data("kendoGrid");
            var options = localStorage["kendo-grid-options"];
            if (options) {
                grid.setOptions(JSON.parse(options));
            }
        });

        //Save grid settings so they can be reloaded later.
        function grid_dataBound() {
            var grid = $("#grid").data("kendoGrid");
            localStorage["kendo-grid-options"] = kendo.stringify(grid.getOptions());
        }
    </script>
