Issue with radio button in AdvStringGrid

Hi,
Windows 10 x64
Delphi 10.4.1
TMS VCL UI Pack v10.4.7.0

If you add multiple radio buttons in a cell, clicking on the 4th or later radio button doesn't work properly.
You can reproduce with the following code:

procedure TForm1.FormCreate(Sender: TObject);
var
  items: TStrings;
begin
  AdvStringGrid1.DefaultRowHeight := 100;
  AdvStringGrid1.Options := AdvStringGrid1.Options + [goEditing];

  items := TstringList.Create;
  for var i := 0 to 6 do
  begin
    items.Add(i.ToString);
  end;

  AdvStringGrid1.AddRadio(1, 1, 0, -1, items);
end;

Click radio 0 --> ok
Click radio 1 --> ok
Click radio 2 --> ok
Click radio 3 --> ok
Click radio 4 --> doesn't work nothing happens
Click radio 5 --> radio 4 ends up selected
Click radio 6 --> radio 5 ends up selected

Is this a bug that be be fixed please?

Thanks
