I have created a TEST Template, which contains only a few items to get "familiar" with the Automatic Inventory part of zabbix

Here are the Items of my Template:

The problem I have is with the Agent_Hostname and Check_Manufacturer items, Here is the configuration of the Agent_Hostname item :

As I understand it, it is configured to fill the "Name" field of the inventory tab, And here is the configuration of my Check_Manufacturer item :

Configure to fill in the Manufacturer field of the inventory tab, I go to the Lastest Data menu to see what values are returned by these 2 objects :

I can see that these are the 2 good values that are brought up by my objects, But when I go to the inventory tab of zabbix, i see :

it filled in the "Name" field with the value of the "Check_Manufacturer" item, it put the value of the Agent_Hostname item in the "Location" field and it left the "Manufacturer" field empty, even though this is not the way I configured my items 

And I would like to know why zabbix does not respect the configuration of my items
