Hey i am not sure this is a template problem looks like Zabbix problem.
I use template_bind_stat.yaml ( https://github.com/zabbix/community-templates/blob/main/Applications/DNS/template_bind_stat/6.0/template_bind_stat.yaml )
After maintenance with no data collection end i get strange graph. Looks like he show in 1 minute all DNS requests from whole maintenance...

Reproduce:

Install Zabbix 6.0
Import https://github.com/zabbix/community-templates/tree/main/Applications/DNS/template_bind_stat/6.0
Create maintenance with no data collection - the best create 1 hour or more
After 1 hour ( when maintenance end ) check Graph "Queries IN"

I report same on Community forum: https://github.com/zabbix/community-templates/issues/204 but i get information possible this problem with Zabbix not template.

Best Regards
TaKeN
