sInfo text for Print and Copy buttons Not working

Below is my setup to the datatable using tabletools. My issue is i cannot get the "sInfo" text to be displayed when Copy or Print buttons are being used. It always display a empty white box.

Am i missing something? or is this a issue in TableTools?

Thanks

                    $(document).ready(function()
                    {
                    oTable = $('#FIELD_NUM_71').dataTable(
                    {
                    "sScrollX": "100%",
