RibbonTabControl Disappears

[Son]

When using the ribbon tabbing control and adding buttons in the controls. Often in design view the tabs will disappear.. When you compile and run sometimes they show up and sometimes they dont..After you close the application and go back to the ui verify inconsistently the tabs disappear nowhere to be found at all..When you go to the designer code everything is there but I have noticed that every once in a while The following lines of code disappear.

code:
this.ribbonControlAdv1.Header.Items.AddRange(new System.Windows.Forms.ToolStripItem[] {
this.transactionsTabItem,
this.addEditTabItem});
this.ribbonControlAdv1.Header.Location = new System.Drawing.Point(0, 1);
this.ribbonControlAdv1.Header.MainItems.Add(new

Syncfusion.Windows.Forms.Tools.ToolStripItemAdvInfo(this.transactionsTabItem));
this.ribbonControlAdv1.Header.MainItems.Add(new
Syncfusion.Windows.Forms.Tools.ToolStripItemAdvInfo(this.addEditTabItem))

The only way to stop this from removing its self is putting it in the form.cs construtor..

What can I do to Prevent this....
