Creating Controls in a TScrollBox at Runtime Starts to ReOrder

  

I’m using Delphi 10.1 and Firemonkey and looking to add controls to a TScrollBox at Runtime and have come across some strange behaviors.
For this example I create Labels and add them to a TScroll box.
The Label is set as TAlignLayout.Top so I assume every new Label created will sit below the previous.

First Label that gets created goes to the top.
Second Label that gets created goes below the first.
Third Label that gets created goes between the first and second
Label.
Any more Labels that created then stacks under the First Label.

I want the Labels to be created from top down in order of creation. Any ideas what I’ve done wrong?
This is the code to create the Labels:-
procedure TForm1.Button4Click(Sender: TObject);
var
lbFileDate: TLabel;
begin
ScrollBox2.BeginUpdate;
lbFileDate := TLabel.Create(ScrollBox2);
lbFileDate.Parent := ScrollBox2;
lbFileDate.Align := TAlignLayout.Top;
lbFileDate.Text := DateTimeToStr(Now);
ScrollBox2.EndUpdate;
end;

I’ve done something very similar in Delphi 10.1 VCL and the creation process works by always putting the last Label to the top.
