Backup a database from Azure SQL Managed Instance and restore to on premise SQL Server
 I have my database in managed instance. and i extracted dacpac using SSTD but now when i try to deploy extracted file using SSMS. I am getting following error:

Could not deploy package.
Error SQL0: The element [releaseengineer] cannot be deployed. This element contains state that cannot be recreated in the target database.
Error SQL0: The element [Reporter] cannot be deployed. This element contains state that cannot be recreated in the target database.
 (Microsoft.SqlServer.Dac)
Have a look at the commentary here. Has the login been created on each instance using the same SID?  If not then this might be the cause of the issue.
