Steps to reproduce:

1. Following the steps in [PostgreSQL by Zabbix agent

   https://github.com/zabbix/zabbix/tree/release/6.4/templates/db/postgresql]

Result:
The preprocess steps are reverted in the host item, the item name is Checkpoint: Checkpoint sync time per second

Retried multiple times by deleting and creating the host from the template, but not working.

Expected:
Steps order should remain the same as what defined in the template
