When using latest version of Zabbix Frontends - trunk and trying to export Template, for example, Template_AIX on preview screen all items are shown, but only these lines are exported (see files attached):

<?xml version="1.0" encoding="UTF-8" ?>

• <zabbix_export version="1.0" date="20.01.10" time="13.05">
• <hosts>
• <host name="Template_AIX">
  <proxy_hostid>0</proxy_hostid>
  <useip>0</useip>
  <dns>Template_AIX</dns>
  <ip />
  <port>10050</port>
  <status>3</status>
  <useipmi>0</useipmi>
  <ipmi_ip />
  <ipmi_port>623</ipmi_port>
  <ipmi_authtype>0</ipmi_authtype>
  <ipmi_privilege>2</ipmi_privilege>
  <ipmi_username />
  <ipmi_password />
  <groups />
  <triggers />
  <items />
  <templates />
  <graphs />
  <macros />
  </host>
  </hosts>
  <dependencies />
  </zabbix_export>
