Delete button dont work

Delete should work. Are you able to wiew/edit entries?

You can use the filter_entries filter to add the post status to the list like so:

Add a field to your form, give it the name “Status” and note the ID of that field. Then add this code to your functions.php

add_filter('filter_entries','add_entry_id' );
function add_entry_id($entries) {
    foreach ($entries as &$entry) {
        $entry["xxx"] = get_post_status($entry["post_id"]);
    }
    return $entries;
}

Change xxx in the code above to the ID of your new field.
