Backup Set not showing in Restore Files > Restore From > View All

I have 4 computers, and I use Norton Backup to back them up onto a single local network drive where I store all my backups. I am trying to use Norton Backup to copy all of the files from one older computer onto a new computer. When I go to Norton 360 Restore Files and try to select the backup set in the Restore From section, I click View All, but none of my Backup Sets from any of my computers appear. All of these Backup Sets were created using the same Norton Account. Screenshot 2024-02-05 062421.pngScreenshot 2024-02-05 062457.png

I have 6 computers doing backups to cloud storage, and I want to restore a folder from one of the backups to another computer.  As above, in the "Restore From", a "View All" does not show me all of the backups.  At first, I could only see the backup from the computer I was trying to restore to.  I rebooted, and could then see 4 backups, but not the particular one I wanted to restore from.

As an alternative, I thought I could instead use "Restore online backup using a browser".  There, I can see all of my 6 backups.  However, that interface is very restrictive - it seems I can only restore one file at a time!  I want a folder containing sub-folders and quite a few files.  Why is that restore using a browser so restrictive?
