Unknown error occured. Blivet-gui will be terminated. could not find parent for subvol

Blivet-gui works initially with Fedora 27. When I keep creating btrfs subvol, and suddenly it refuse to load afterwards.

This is the "Show traceback" under Fedora 27.

After I remove all old subvol, then blivet-gui is loading fine.
