Alert state chagne from Alert to OK, issue with templating variable

I’m using ${instance} label in alert message. When I received email for Alert state its parsing ${instance} correctly. But when I’m getting email for OK state, in email message ${instance} as it is.

Which version of grafana and grafana alerting (legacy or new grafana alerts) are you using?

thanks for replying!
I am using Grafana v8.5.2 and legacy alerts.

it resolved in latest versions of grafana > v9.0
