Why PropertyGrid generate excess properties, when AutoGeneratePropertyDefinitions is set to false?

<Window x:Class="PropertyGridTester.MainWindow"

            <ColumnDefinition Width="*" />
        </Grid.ColumnDefinitions>
          
        <StackPanel Grid.Column="0">
            <RadioButton Command="{Binding SetFirstClass}">Set first class</RadioButton>
            <RadioButton Command="{Binding SetSecondClass}">Set second class</RadioButton>
            <RadioButton Command="{Binding SetNull}" IsChecked="True">Set null</RadioButton>
        </StackPanel>

Hello,

We have had a similar issue with RadPropertyGrid placed in a DataTemplate with some older versions. Would you please confirm which version of RadControls you are currently using?

All the best,
