Steps to reproduce:

1.  I updated to Zabbix 7.4.0rc1 on my Raspberry Pi 4 running on Raspbian OS 12: https://whatsuphome.fi/whatsuphome/part122 
2. Tried to go to fancy new Host Wizard but only saw "No data" under Select a template part
3. After I updated some of the templates to Zabbix 7.4 templates from git.zabbix.com, I got to see results for those templates. 

Result:

Expected:

I thought I would see all the usual templates even though they were not from a fresh Zabbix install, but rather my What's up, home? Zabbix that's been around since March 2022 and survived through all the updates, from .. what, Zabbix 6.0? 6.2? Something like that. 

Instead, seems like that Zabbix 7.4.0rc1 does not support the templates from older Zabbix versions.
