Steps to reproduce:

1. Go to git.zabbix.com
2. Download template for version 7.0, for example: https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/app/zabbix_proxy/template_app_zabbix_proxy.yaml?at=refs%2Fheads%2Frelease%2F7.0
3. Try to import it in Zabbix 7.0

Result:
You will get the following error:

This is due, for some reason, to the following part of the template:

          preprocessing:
            - type: CHANGE_PER_SECOND

If you change every occurrence to the following, you will be able to go ahead:

          preprocessing:
            - type: CHANGE_PER_SECOND
              parameters:
                - ''

But even after changing all occurrences, if you try to import the template, you will get the following error:

But this time I'm unable to locate in the template what this is related to.

Expected: Successful import
