Right-Click Delete button disappared on Excel 2010

[GrilledCheese]

When I right-click on any cell in the worksheet, the "delete" button is missing. What's the fix to bring the "delete" button back? I can delete columns and worksheet tabs but not any cell.

See if running this code helps

Sub Defaultcellmenu()
    CommandBars("Cell").Reset
End Sub
