Odd snapshot subvolume

["Brian J. Murrell" <brian@interlinx.bc.ca>]

On my Fedora system I have the following:

$ sudo btrfs subvolume show /
fedora_root
	Name: 			fedora_root
	UUID: 			c08a988c-ddd5-164e-b01e-51ac26bf018b
	Parent UUID: 		-
	Received UUID: 		-
	Creation time: 		2021-08-10 18:30:03 -0400
	Subvolume ID: 		258
	Generation: 		5029586
	Gen at creation: 	10
	Parent ID: 		5
	Top level ID: 		5
	Flags: 			-
	Send transid: 		0
	Send time: 		2021-08-10 18:30:03 -0400
	Receive transid: 	0
	Receive time: 		-
	Snapshot(s):
				fedora_root/previous-releases/f38_root
				fedora_root/previous-releases/f39_root
				fedora_root/previous-releases/f40_root.old
				fedora_root/previous-releases/f41_root
				previous-releases/f33_root
	Quota group:		n/a

All of the fedora_root/previous_releases/* snapshot subvolumes make
sense to me.  There are all accessible at:

$ ls -l /previous-releases/
total 0
dr-xr-xr-x. 1 root root 378 May 31  2023 f38_root
drwxr-xr-x. 1 root root 194 May 31  2023 f38_var
dr-xr-xr-x. 1 root root 378 Nov 11  2023 f39_root
drwxr-xr-x. 1 root root 194 Apr  1  2024 f39_var
dr-xr-xr-x. 1 root root 362 Jun 15  2024 f40_root.old
drwxr-xr-x. 1 root root 194 May 15  2024 f40_var.old
dr-xr-xr-x. 1 root root 362 Jun 15  2024 f41_root
drwxr-xr-x. 1 root root 194 May 15  2024 f41_var

But then there is that odd-duck snapshot "previous-releases/f33_root"
not under "fedora_root" and not showing under /previous-releases in the
filesystem's namespace.

How can I access that "previous-releases/f33_root" snapshot or even
just remove it?

Cheers,
