No link between suppliers list on glpi and the supplier plugin list

[snoopspeed]

Dear all, we installed the plugin order management.
Glpi version : GLPI 10.0.6
Plugin order : last version 2.10.4

On the plugin, we create new order. When we tried to select on the list the supplier, we have a empty list. When i select the i, we forwarded to the supplier list and we will seee all suppliers. After checking the table on the plugin, we see we have a specific table dedicated to suppliers.
the field location : ok
the field contact and suppliers : empty on the plugin.

thank you for your help

the contract of the supplier must insert to the 'contact' first, because the contact is not getting from the supplier.
hope this can help you
