Admin password not being pushed to DB

We have Grafana v7.0.3, deployed over AKS.
We upgrade/deploy new Grafana instances using Helm.

Since we upgraded to Grafana v7.0.3, deployment or upgrade attempts succeed, but the newly generated admin password is not pushed to the Grafana mysql database.

I can login with the previous admin password and i can edit the mysql database, but those are workarounds and shouldn’t be they method to accomplish this.

I’ve tested this scenario on v6.7.3 (by uninstalling the Grafana instance and dropping all tables in the database, then installing the v6.7.3 Helm chart), and each time I upgraded or redeployed the instance, the password pushed to the database without issues.

Any advise would be appreciated.

Thank you
