Only help submenu visible on Install

[Nikhil Parachure]

HI 

I have recently published an add-on. But on install only help submenu shoes up and after refreshing page all other sub menus show up. Any idea why this is happening ?

code is 

function onOpen(e) {

  SpreadsheetApp.getUi().createAddonMenu()

      .addItem('Create ', 'newSheet')

      .addItem('Build ', 'buildURL')

      .addItem('Build1', 'buildURL1')

      .addToUi();

}

Thanks in advance for help.
