Formatting problem when place the control in double level TableLayoutPanel


I have a TableLayoutPanel.

In the first row an another TableLayoutPanel is inserted (second level).

When I place the SfNumericTextbox inside this second TableLayoutPanel and change the cotrols AllowNull property to True and change the value empty, the backcolor of the control will be dark gray (in designer and realase mode too).

When I type anything to the control, the backcolor will be good again. The problem appear in empty control only.

I attach a sample too. Can you help me please solve this problem?

Thank you very much!
