Did you type it incorrectly?  What release?

You seem to show {non-exist,corrupt} lock sectors, which can result
from bad passphrase.

src/sys/geom/bde/g_bde_lock.c:
370:        /* If it points ito thin blue air, forget it */
371:        if (off + G_BDE_LOCKSIZE > (uint64_t)mediasize) {
372:                off = 0;
373:                return (EINVAL);
374:        }
...
435:        /* If we have an unsorted lock-sequence, refuse */
436:        for (i = 0; i < G_BDE_MAXKEYS - 1; i++)
437:                if (gl->lsector[i] >= gl->lsector[i + 1])
438:                        return (EINVAL);

/usr/include/sys/errno.h:
