Backup Sets

I have 6 backup to disk jobs that all backup to a NFS share each in a separate folder and each created separately as a disk based storage. I configured the jobs to run a full back up and then a differential backup . The backups run successfully and they backup in the correct shared folder but in the GUI in the server’s backup sets it combines all the backups of all the jobs for each one. Under the storage it creates just the instance of what was backed up.
