Incorrect query in a copied list

[dranreb_38]

Hello
I just copied a well-working list in order to make another form accessing the same database.
When I try to access to the list, I get the message:

500 Fabrik has generated an incorrect query for the list Achat/Réservation: <br /><br /><pre>Champ '8' inconnu dans order clause</pre>
C:\wamp\www\gastronamis\components\com_fabrik\models\list.php:937

I use Joomla 3.8.10 and Fabrik 3.8.1, PHP 7.x

Seems to be an old story when I look at the forum. A simple may to solve it ?

The copied list has new elements which may be unpublished (depending on your settings in Fabrik Options).
Make sure the elements you need are published and go to your new list settings "Data" and select the correct element(s) you want to use for ordering.

And make sure that the primary key is set correctly.
