Server side send "auto" in filter

A77ak

I'm having an odd issue related to server side processing using filter in some columns. Sometime, apparently in a random way, the server is receiving in filter1 (d.filter1) the value "auto", which is not an option in the select combo. Is there any way to avoid this?

Here is my code:

 <div class="data-table">
      <table id="js-table" class="table">
           <thead>
                <tr>
                     <th class="filter">Col1</th>
                     <th class="filter">Col2</th>
                     <th>Col3</th>
                     <th>Col4</th>
                     <th>Col5</th>
                </tr>
           </thead>
      </table>
      <div class="selects"></div>
 </div>

 var $tableCon = $('.data-table:eq('+ 1 +')');
 var $table = $tableCon.find('.table');

 var dataTable = $('#js-table').DataTable( {
      "processing": true,
      "serverSide": true,
      "bFilter": false,
      "ordering": false,
      "bLengthChange": false,
      "ajax": {
    "url": "/agetdatatableaspx",
    "type": "POST",
    "data": function ( d ) {
        var selects = document.getElementsByTagName('select');
        if (selects.length > 0){
            d.filter1= selects[0].value;
            d.filter2 = selects[1].value;
        }
    }
 },
 initComplete: function(){
      if (this.fnSettings().fnRecordsTotal() > 0){
              $tableCon.find('.selects').insertBefore($('#js-table-hist'))

           var counter = 0;
           dataTable.columns('.filter').every( function (e) {
                 var column = this;
                 $tableCon.find('.selects').append('<div class="select-holder"><label><span class="label">'+ $table.find('thead th:eq('+ e +')').html() +'</span><select><option value="">- Todos -</option></select></label>');
                  var select = $tableCon.find('.selects .select-holder:eq('+ counter +') select')
                           .on( 'change', function () {
                                var val = $.fn.dataTable.util.escapeRegex($(this).val());
                                 column
                                      .search( val ? '^'+val+'$' : '', true, false );
                                      dataTable.draw();
                             });
                  column.data().unique().sort().each( function ( d, j ) {
                       select.append( '<option value="'+d+'">'+d+'</option>' )
                  } );

                counter++;
            } );
     }
 });

Weird. DataTables shouldn't be setting a filter to auto ever, unless told to do so by an API call. It has no special meaning in DataTables the word "auto".

Are you able to give me a link to the page showing the issue?
