It's a bug, thanks for reporting it.
The underlying problem is that in both cases no bucket_id was specified,
so it defaults to the same value in each case, and duplicate bucket IDs
were not correctly handled. You can avoid the problem by specifying a
different bucket_it in your "insert-buckets" command.
I posted a fix. You can test it by applying the following two patches,
in this order:
