Help with Backup-DbaDatabase script

[luisflavio]

Hi guys,
Could you please help me if I missing anything about generating Backup File Name since the script Backup-DbaDatabase is generating wrong name to the second database.

I'm executing the script below:
Backup-DbaDatabase -SqlInstance SERVER\SQL2014 -Database DB1,DB2 -CopyOnly -Checksum -Verify -ReplaceInName -Path 'C:\Backups\Databases\instancename\dbname\backuptype' -BackupFileName instancename_dbname_backuptype_timestamp.bak -TimeStampFormat yyyyMMdd_HHmmss

The first backup database file is generating with right name (SQL2014_DB_Full_20210625_130931) but the DB2 is generating with wrong name (DB2_20210625_130618) it is missing the instancename.

Sorry to say, but "works on my machine". Please update to the latest version of dbatools and try again. If it still fails, you might want to open an issue.
