Restore individual files from incremental vm backup successful and 0 bytes

I use Backup Exec 2012 with GRT. I make full backups of all VM's thorugh virtual center server on friday and on weekdays incremental backups.

The backups were successfull. All the VM's have the Backup Exec agent installed.

I tried to restore some individual files from a wednesday to the original location. The job completes successfully, but the byte count is ZERO.The are no files restored. I also tried to restore the files to a different location, but also nothing is restored and the job is successful with 0 bytes.

Anyone else with the same issue? What's going on?
