When you show the Marks in a CircularGauge, the Marks.Items are serialized and then the Mark is out of sync with the Arrow Value.

To reproduce the problem:

- Add a CircularGauge Series to a new Chart.
- Set Marks Visible.
- Change the Value at "Format/Options/Value" tab.
- See the form in "Text View" (Alt+F12). You'll see the Marks.Items are serialized
- Go back to the "Form View"

Now the Mark isn't in sync with the arrow value (and the legend).

The workaround is to clear the Marks.Items. This can be done at the form in "Text View" or by code:

procedure TForm1.FormCreate(Sender: TObject);
begin
  Series1.Marks.Items.Clear;
end;
