How do I change the dock property of the control tab to not be overridden on customization when Personalizations?

When designing I will focus but users they can go to Personalizations they press focus will have this situation :thinking: :thinking:
grpFilter.Dock=DockStyle.Top;
AddTab();
//grpFilter.SendToBack();

	grdData.Dock=DockStyle.Fill;
	grdSumPart.Dock=DockStyle.Fill;

	grdMadtl.Dock=DockStyle.Fill;
	grdSVG.Dock=DockStyle.Fill;
	grdLabor.Dock=DockStyle.Fill;
	grdMFGSTK.Dock=DockStyle.Fill;	

When I focus on the groupbox above, the tab below will be hidden under the groupbox

Thank you! Have a good day!
