This worked for me, now I can see the list, but how delete the folder? I assume rm will not work?
# btrfs subvolume delete -c /path
using the fully qualified folder name (/data/... )
The -c tells btrfs to wait for the deletion to complete. You can omit that if you want.

Will come back in a day or so to confirm and accept the solution!
So I checked the drive just then, and it has reclaimed all the space that was wasted! Now I have another 1.3TB available! Thanks!

Great!. If you've never run a balance, then you might want to do that (it's run from the volume settings wheel).
You can set up a volume maintenance schedule there - personally I run each of the maintenance tasks (balance, scrub, defrag, disk test) once every three months. Balance in particular can take a long time if you've never run it, but that will speed up if you run it regularly.
