RadzenNumeric - problem with double type

Hi, I try to use RadzenNumeric with double type and validation, like this:

<RadzenDataGridColumn TItem="ProductTemplateCompositionItemViewModel" Property="Quantity" Title="Ilość">
    <EditTemplate Context="item">
        <RadzenNumeric TValue="double" Step="0.5" @bind-Value="@item.Quantity" Name="QuantityNumeric"/>
        <RadzenNumericRangeValidator Min="0.0001" Max="10000.0" Text="Podaj ilość komponentu" Popup="true" Component="QuantityNumeric" />
    </EditTemplate>
</RadzenDataGridColumn>

As you can see this is inside inline form.
Anyway, I get the error: Argument 1: cannot convert from 'double' to 'dynamic'

my @itemQuantity is of type double.
What's more, when I try to use Min and Max properties withing double type on RadzenNumeric I get the error also.

My Radzen version: 3.20.3

Maybe DataGrid TItem is dynamic?

No, it's concrete type:

<RadzenDataGrid @ref="grid"
                AllowFiltering="false"
                AllowColumnResize="true"
                AllowGrouping="false"
                AllowMultiColumnSorting="false"
                AllowRowSelectOnRowClick="false"
                TItem="ProductTemplateCompositionItemViewModel"
                Data="@CompositionItems"
                EditMode="DataGridEditMode.Single">
...

I'm afraid that I'm unable to reproduce this:
