avoiding row-selection when sorting click

I Just Show test code and GIF capture.

// With default AdvStringGrid, Initiation by Duble-Click
procedure T2S.asg2DblClick(Sender: TObject);
begin
  with asg2 do
  begin
     MouseActions.CheckAllCheck := true;
     MouseActions.DisjunctRowSelect := true;
     MouseActions.DisjunctRowSelectNoCtrl := true;
     MouseActions.HotmailRowSelect := true;
     MouseActions.RowSelect := true;

     Navigation.MoveRowOnSort := true;

     Options := Options + [goRowSelect, goRangeSelect];

     RandomFill(false);

     ClearRowSelect;
     SortIndexes.Clear;
     SortSettings.Show := false;
     SortSettings.Show := true;
     SortSettings.IndexShow := true;
  end;
end;

When Click column header for sorting
some row is selected like this,
Animation

What could I do to avoiding row-seelction?
(Actually row-selecting is worked just click anywhere)
