Filter Descriptor contains two "magic" items in context.FilterDescriptor when TelerikMultiSelect component is empty.

I use TelerikMultiSelect as a component for custom filter:

<FilterMenuTemplate>
    <TelerikMultiSelect Value="@(AlreadySelectedFilterValues(context.FilterDescriptor))"
                        OnRead="@OnReadWrapper"
                        ValueMapper="@ValueMapperWrapper"
                        TItem="@FilterItemDto" 
                        TValue="@TFilterValue"
                        ValueField="@nameof(FilterItemDto.Id)"
                        TextField="@nameof(FilterItemDto.Name)"
                        AutoClose="true"
                        Filterable="true"
                        ClearButton="true"
                        DebounceDelay="500"
                        OnChange="@((object newValue) => OnMenuFilterChange(newValue, context))"/>
</FilterMenuTemplate>

Trying to render already selected filters gives two "magic" items in context.FilterDescriptor in AlreadySelectedFilterValues:

These items appear only if TelerikMultiSelect is empty. If I select some from MultySelect these two items disappear and everything works as expected.

GridState has an empty list of FilterDescriptos.
AggregatedAccountNames - string? column.
TFilterValues can be int, int? or string, no matter, the same behavior.
TFilterItemDto - class with int? Id and and string Name fields.

As expected value I expect to have empty FilterDescriptos if nothing was selected.

Hi Vladimir,

Can you please confirm if you are referring to the ExpressionBuilderOptions field?

In order to evaluate the issue, please provide an isolated runnable sample that reproduces the described behavior. Please share details on what problem this introduces and list the exact steps to perform, so I can replicate it on my end.

Thank you in advance for your cooperation!
