RadDataGrid throwing odd XAML binding errors

I have just implemented a MAUI ContentPage with an completely empty RadDataGrid definition. In my "using" section of the xaml page, I have this entry:

xmlns:dataGrid="http://schemas.telerik.com/2022/xaml/maui"

In the root grid, I have this entry:

<dataGrid:RadDataGrid
	Grid.Row="1">
</dataGrid:RadDataGrid>

When the application is run, I get the following XAML binding errors:

NotificationsViewModel	ActualWidth	RadBorder.MinimumWidthRequest	Double	'ActualWidth' property not found on 'MobyClient.ViewModels.NotificationsViewModel', target property: 'Telerik.Maui.Controls.RadBorder.MinimumWidthRequest'
NotificationsViewModel	HeaderText	Label.Text				String	'HeaderText' property not found on 'MobyClient.ViewModels.NotificationsViewModel', target property: 'Microsoft.Maui.Controls.Label.Text'

A key point is that when I added 'ActualWidth' and 'HeaderText' observable properties, the errors go away. In fact, when I run the Telerik MAUI code examples, I see the same errors in the examples "First Look" data grid example:

Telerik.Maui.Controls.Compatibility.DataControlsRenderer.UWP.ExtendedListViewItem	HandleIconPath	Microsoft.UI.Xaml.Controls.BitmapIcon.UriSource, Name='PART_ReorderHandle'	Uri	BindingExpression path error: 'HandleIconPath' property not found on 'Telerik.Maui.Controls.Compatibility.DataControlsRenderer.UWP.ExtendedListViewItem'			
FirstLookViewModel	ActualWidth	RadBorder.MinimumWidthRequest	Double	'ActualWidth' property not found on 'QSF.Examples.DataGridControl.FirstLookExample.FirstLookViewModel', target property: 'Telerik.Maui.Controls.RadBorder.MinimumWidthRequest'			
FirstLookViewModel	HeaderText	Label.Text				String	'HeaderText' property not found on 'QSF.Examples.DataGridControl.FirstLookExample.FirstLookViewModel', target property: 'Microsoft.Maui.Controls.Label.Text'

Obviously, I either missing something in the Telerik MAUI control setup or there is a bug. Is this a setup issue or a bug? I am also seeing similar binding errors in the RadListView. As a general rule, I do NOT like any binding errors, so this bugs me. Any ideas?
