TTMSFMXGrid style question

I notice something odd. By default, the column FixedFont is bold and the Font is not. When I change the FixedFont bold (to false) and size (to 15 instead of Default), first item is still displayed in the default (smaller) font size. Clicking on it fixed this and it changes to the desired size 15. Also, the last row in the grid is still displayed in a Bold font and tends to have the styling of the fixed row.

Any input?

I have retested this here with the code:

procedure TForm1.Button1Click(Sender: TObject);
  TMSFMXGrid1.Columns[0].FixedFont.Size := 20;
  TMSFMXGrid1.Columns[0].FixedFont.Style := [];

procedure TForm1.FormCreate(Sender: TObject);
  TMSFMXGrid1.UseColumns := true

but this works as expected.

I used the Object Inspector to set values, maybe that should be done programatically, not sure if that makes a difference but I will test. (And I am using C++ but I do not see why that should matter)

When you use the object inspector, is the issue at designtime and runtime or only at designtime?

It is at runtime. But I "fixed" the problem using the CellLayout event:

    ALayout->Font->Size = DMUI->DEFAULT_FONT_SIZE();

I could not reproduce this here so far. 
Do you have some sample source project with which we can see the problem here?
