Bootstrap form select не правильно работает

Почему select не правильно отобразился? Хотя он и там и там один и тот же.

    <div class='box box-theme box-form'>
  <div class='box-header with-border'><h4 class='box-title'>_{SPLITTERS}_ : %WELL%</h4></div>
  <div class='box-body'>
    <form name='CABLECAT_COMMUTATION_ADD_MODAL' id='form_CABLECAT_COMMUTATION_ADD_MODAL' method='post'
          class='form form-horizontal ajax-submit-form'>
      <input type='hidden' name='index' value='$index'/>
      <input type='hidden' name='operation' value='ADD'/>
      <input type='hidden' name='entity' value='SPLITTER'/>
      <input type='hidden' name='ID' value='%COMMUTATION_ID%'/>
      <input type='hidden' name='COMMUTATION_ID' value='%COMMUTATION_ID%'/>
      <input type='hidden' name='CONNECTER_ID' value='%CONNECTER_ID%'/>
      <div class='form-group'>
        <label for='SPLITTER_ID' class='control-label col-md-3'>_{SPLITTER}_</label>
        <div class='col-md-9' id='SPLITTER_ID'>
          %SPLITTERS_SELECT%
        </div>
      </div>
    </form>
  </div>
  <div class='box-footer'>
    <input type='submit' form='form_CABLECAT_COMMUTATION_ADD_MODAL' id='CABLECAT_SPLITTER_ADD_BTN' class='btn btn-primary' name='submit'
           value='%SUBMIT_BTN_NAME%'>
