Renaming a drive doesn't seem to work

I have an external hard drive that I use for backups. I renamed it Backup Drive, but in D.Opus it says "Roboform2Go". Now, I do have Roboform to Go, and it was open at the time I renamed the drive, but I can't figure out what to do. I opened a command window and everything looks OK. It just doesn't in D.Opus. Thank you for any and all help!

What label is shown for that drive in Windows Explorer?
