My custom box is ONLY showing the label for Center and I don't know why, I have tried removing the left and right labels (label="Left"), changing their names, however it only ever shows center and the others have no labels at all


<box id="box3" boxStyle="vertical">      
      <control idMso="AlignLeft" label="Left" />
      <control idMso="AlignCenter" label="Center" />
      <control idMso="AlignRight"  label="Right" />
</box>
