Duplicated results per row - php

Question

I run a query, the result is good, but while putting into PHP result, the resuts are duplicated per row, here is the code:
$selectSi = 'SELECT * FROM series LEFT JOIN series_join on series.ids = series_join.id_sil GROUP BY series.ids';
$querySi = $connexion->query($selectSi);
$resultSi = $querySi->fetchAll();
$displaying = 5;
// building table here
foreach($resultSi as $siK=>$siV)
{
$ids = $siV['ids'];
$silsila_en = $siV['silsila_en'];
$id_shks = $siV['id_shks'];
// get singer
$sSel = 'SELECT shk_fname, shk_lname, shk_tran FROM shk_tbl WHERE id_shk = "'.$id_shks.'"';
$sReq = $connexion->query($sSel);
$sRes = $sReq->fetchAll();
$listShk = '';
foreach($sRes as $vS)
{
$shk_fname = $vS['shk_fname'];
$shk_lname = $vS['shk_lname'];
$shkFullName = $shk_fname.' '.$shk_lname;
$shkFullNameLink = '<a href="">';
$shkFullNameLink .= $shkFullName;
$shkFullNameLink .= '</a> - ';
$listShk .= $shkFullNameLink;
$listSheikhs = substr($listShk, 0,-2).'<br />';
}
// putting result into a table
echo '<tr class="multiColor">';
echo '<td>'.$silsila_en.'</td>';
echo '<td>'.$listSheikhs.'<br /></td>';
echo '</tr>';
}
echo '</table>';
and the tables are like this
PS: Instead of numbers result, it is singers name
I am looking for a result like:
Conciseness of speech: 114 - 136
The eternal journey: 325 - 326 - 327
Night Mare: 303 - 332 - 331 - 330 - 329 - 328 - 282 - 306 - 281 - 126 - 120
but I am getting something like:
Conciseness of speech: 114 - 136
The eternal journey: 114 - 136 - 325 - 326 - 327
Night Mare: 114 - 136 - 325 - 326 - 327 - 303 - 332 - 331 - 330 - 329 - 328 - 282 - 306 - 281 - 126 - 120
so the first row is duplicated to second, and second is duplicated to third
Thanks in advance
