Steps to reproduce:

1. Create template with item and trigger
2. Export created template

   zabbix_export:
     version: '6.0'
     date: '2023-08-25T07:23:20Z'
     groups:
       - uuid: 0dad8812c0464f75964fee1b81c226b4
         name: AAA
     templates:
       - uuid: 3305be7494754639960af36f3f814100
         template: AAA
         name: AAA
         groups:
           - name: AAA
         items:
           - uuid: b9bc953edce447acafe31f8007da982c
             name: a
             key: a
             triggers:
               - uuid: 76f19a0db027464289ebcb9c375c4172
                 expression: last(/AAA/a)=0
                 name: b
   
   

3. Delete created template 
   or use file instead of 1-3 steps zbx_export_templates_6.0.yaml
4. Open Configuration -> Hosts
5. Import file
6. See misleading message about host - Incorrect trigger expression. Host "AAA" does not exist or you have no access to this host.
7. Create host with the same name as template
8. Try to import again
9. See misleading message about item key - Incorrect item key "a" provided for trigger expression on "AAA".
10. Add item with requested key on host
11. Import again

Result:
template trigger added to host
Expected:
No misleading messages and template trigger not added to host
