Second query on mysqli_multi_query return nothing

Question

I have this php code:

    // Sentences
    $sqlsentence  = "CALL getPartidos_All(0, 25, 2, 20, NULL, NULL);";
    $sqlsentence .= "CALL getNumRows";

    if (mysqli_multi_query($con, $sqlsentence)) {  // RETURN TRUE

        // First query result
        if ($result = mysqli_store_result($con)) {  // RETURN TRUE
            print '<table border="1">';
            while ($fila = mysqli_fetch_row($result)) {
                print '<tr>';
                print '<td>'.$fila[0].'</td>';
                print '<td>'.$fila[1].'</td>';
                //...and so on
                print '</tr>';
            }
            print '</table>';
            mysqli_free_result($result);
        }


        // Second query result
        if (mysqli_more_results($con) && mysqli_next_result($con)) { // RETURN TRUE
            if ($resultRows = mysqli_store_result($con)) {  // RETURN FALSE !!
                print '<table border="1">';
                while ($fila = mysqli_fetch_row($resultRows)) {
                    print '<tr>';
                    print '<td>'.$fila[0].'</td>';
                    print '</tr>';
                }
                print '</table>';
                mysqli_free_result($resultRows);
            }
        }
    }

This code retrieve corretly rows at first procedure (CALL getPartidos_All(0, 25, 2, 20, NULL, NULL);).

But return nothing at second procedure, although (mysqli_more_results($con) && mysqli_next_result($con)) returns true. I don't understand.

Both queries work. (I checked it.)
