Error with host inventory when importing hosts

[Rafael Trevisan]

Hello, I have a very large zabbix running without proper housekeeping, I've built another server, but I do not want to import the whole database, just the templates, and hosts, already imported the templates, but when I try to import the hosts, I get this error:

• Two items ("System information" and "Operating system") cannot populate one host inventory field "OS", this would lead to a conflict.

I've tried to remove the item system information from the .xml, but it return a error from the item and line that is missing from the file.
Is there something i can do?
