The RadzenDataFilter doesn't cast the selected value when set to "multiple" causing issues

Radzen.Blazor Components

Not sure if a bug or I am possibly doing something wrong.
Whenever I attempt to set the selected filtering data type of an IEnumerable or IEnumerable the DataFilter component does not correctly cast the filter of the selected values and is instead a string text of the cast command.

Here is some of my code:

Component

<RadzenDataFilter @ref="notifDataFilter" Auto=true Data="userNotifications" TItem="Notification" ViewChanged=@(view => notifDataList.Reload()) FilterCaseSensitivity="FilterCaseSensitivity.CaseInsensitive" ClearFilterText="Clear All Filters" LogicalFilterOperator=LogicalFilterOperator.And >
  <Properties>
    <RadzenDataFilterProperty Property=@nameof(Notification.Action) Title="Action" FilterValue="@finalSelectedActions" Type="typeof(IEnumerable<string>)" FilterOperators=@(new[] { FilterOperator.Contains })  FilterOperator="FilterOperator.Contains">
      <FilterTemplate>
        <RadzenDropDown @bind-Value=@selectedActions Style="width: 100%;" Change=@OnSelectedActionsChange Data=@(new string[] {"Create", "View", "Update", "Delete"}) AllowClear="false" Multiple="true" />
      </FilterTemplate>
    </RadzenDataFilterProperty>
  </Properties>
</RadzenDataFilter>

IEnumerable<string> selectedActions;
IEnumerable<string> finalSelectedActions;

async Task OnSelectedActionsChange(object value)
{
    if (selectedActions != null && !selectedActions.Any())
    {
        selectedActions = null;
    }

    finalSelectedActions = selectedActions;

    await notifPager.FirstPage();
}

When inspecting the notifDataFilter.Filters property the FilterValue is: {System.Collections.Generic.HashSet1[System.Object].Cast()}`

Am I doing something wrong or is there a bug here ? I see the demo component on the site works flawlessly which frustrates me. It works when I move from multiple to a single select on a string contains and anything else but when doing mumltiple value selection is the issue.

Not sure what's the error at your end however there are various DropDown components in our first demo with multiple selection and there are no errors:

Try to debug your app and compare it to our examples.
