glpi 10 transfert asset avec custom field champs listes multiples

[jph7676]

Bonjour,
lors du transfert d'un asset d'entité avec des customs fields, les valeurs des champs listes multiples sont perdues
glpi 10.0.15 fields 1.21.8

To explain further, the problem concerns the multi-valued list.
When we use this, data is lost when an action (backup, mass action, ...) is performed.

Exemple with this additional fields:

I am able to put various data which are well saved:

As soon as you save a change or use mass actions, the data is lost only for the multi-valued list:

I also noticed the problem when trying to use generated objects in code and do the update:

$item = new PluginFieldsTickettestplugin();
$item->getFromDB($item_id);
$item->update(['id' =>$item_id, 'locations_id' => $location->getID()]);

glpi 10.0.15
fileds 1.21.10
