Why doesn't visible: false work?

    var dt_table = $('#radiological').DataTable({
        language: dt_language,  // global variable defined in html
        order: [[ 1, "desc" ]],  //order by column1 or mrn
        lengthMenu: [[10, 25, 50, 75, 100], [10, 25, 50, 75, 100]],
        columnDefs: [

My guess is you have stateSave: true, and you changed the settings but due to the state being saved it reverts back to the previous setting when reloading the Datatable. As a workaround you san use stateDuration and set it to w low value, like 1 second, reload the page and your display is probably correct now. Once its correct you can remove the setting.
