Windows 10 ignores Internet Explorer when using Import-Startlayout

More Windows 10 inconsistencies. Clearly, I have Internet Explorer in my start screen layout xml (Line 10):

<LayoutModificationTemplate Version="1" xmlns="http://schemas.microsoft.com/Start/2014/LayoutModification">
  <DefaultLayoutOverride>
    <StartLayoutCollection>
      <defaultlayout:StartLayout GroupCellWidth="6" xmlns:defaultlayout="http://schemas.microsoft.com/Start/2014/FullDefaultLayout">
        <start:Group Name="Office" xmlns:start="http://schemas.microsoft.com/Start/2014/StartLayout">

          <start:DesktopApplicationTile Size="2x2" Column="0" Row="2" DesktopApplicationID="{6D809377-6AF0-444B-8957-A3773F02200E}\Microsoft Office\Office14\EXCEL.EXE" />

          <start:DesktopApplicationTile Size="2x2" Column="2" Row="0" DesktopApplicationID="{6D809377-6AF0-444B-8957-A3773F02200E}\Microsoft Office\Office14\WINWORD.EXE" />
          <start:DesktopApplicationTile Size="2x2" Column="2" Row="0" DesktopApplicationID="Microsoft.InternetExplorer.Default" />
        </start:Group>
        <start:Group Name="Play and explore" xmlns:start="http://schemas.microsoft.com/Start/2014/StartLayout">
          <start:Tile Size="4x2" Column="0" Row="0" AppUserModelID="Microsoft.BingFinance_8wekyb3d8bbwe!AppexFinance" />
          <start:Tile Size="4x2" Column="0" Row="2" AppUserModelID="Microsoft.BingNews_8wekyb3d8bbwe!AppexNews" />
          <start:Tile Size="2x2" Column="4" Row="0" AppUserModelID="Microsoft.BingWeather_8wekyb3d8bbwe!App" />
          <start:Tile Size="2x2" Column="4" Row="2" AppUserModelID="Microsoft.Windows.Cortana_cw5n1h2txyewy!CortanaUI" />
        </start:Group>
      </defaultlayout:StartLayout>
    </StartLayoutCollection>
  </DefaultLayoutOverride>
</LayoutModificationTemplate>

And when I log in for the first time, I.E. isn’t in the start menu.
Others are having this issue too!
