Quite strange. I didn't see that problem here.

btrfs/006 12s ... 13s
Ran: btrfs/006
Passed all 1 tests

Can you retain the scratch mounted and check what is the output of
'btrfs fi show -m' (when the SCRATCH is mounted).
OR /proc/fs/btrfs/devlist (in case if you have that) would help
to debug this.
OR could you restart test with a wipe all disk ?
Thanks, Anand
