Netbackup attempting to backup a deleted DB

Good day,

This isn't necessarily a problem, but I'd like some info.

Environment:

Master Server: 7.6.1.1

Media Server: 7.6.1.1

Client: 7.5.0.5

I have a SQL diff backup that runs, but it fails on a specific Database. I've asked our SQL DBAs to have a look and they inform me that the problematic DB no longer exists. So the backup is partially successful (1). Is this fixed with a new Full backup? Or is there something I, from an admin side need to do to inform Netbackup that this DB no longer exists?
