Backup & Restore - Manage button doesn't show any files even though there are backups

Issue description:

Under Backup & Restore there’s a Manage button in the “Last Backups” section, but when I click on it the list is empty, even though there are backups. Is it supposed to show anything for backups on [External storage]?

No it’s not it just show the files managed by Symfonium.

Is the Manage button in the wrong place? I noticed that debug.log files show in there, but it’s kinda weird to go to Backup & Restore to delete the debug log files, I’d expect to find it under Advanced settings > Cleanup or Debug for that function.

No it’s not it leads to the same place as manage Symfonium generated file.

Where do I find this “Manage Symfonium generated files”? It is not under “Debug” as described here: Settings - Advanced

Edit: found it under Miscellaneous.
