TTMSFMXGrid repeat sort of grid

FMX TMS FMX UI Pack

TTMSFMXGrid repeat sort of grid.
Version is 2.2.2.4 under Windows 8.

1. Programmatically generate rows in the grid.
2. Click on header.
I can see the triangle graphic in header cell.
The rows are sorted.
3. Programmatically generate rows in the grid.
I can see the triangle graphic in header cell.
4. Click on header. Perhaps click on header again.
I can see many blank rows at top then the sorted rows beneath.

I tried :-
var
  ModeSave : TTMSFMXGridSortingMode;
begin
 ModeSave := gridSearchTreeshts.Options.Sorting.Mode;
  gridSearchTreeshts.Options.Sorting.Mode := gsmNone;
  gridSearchTreesh*ts.Options.Sorting.Mode := ModeSave;

Unfortunately that did not fix the problem.
How can I "reset" the grid?

Can you use a BeginUpdate / EndUpdate to wrap your code of clearing the sortmode?

Thank you for that reply.
I have now experimented and found a partial fix :-

1. At event FormShow save the property gridSearchTrees.RowCount
2. Restore RowCount before adding rows.

There is still the problem of the sort triangle graphic seen in a Header cell.
I can live with this. However it would be nice to remove any Header cell sort triangle graphics.
