Sustain pedal question.

[Hwaen Ch'uqi]

Greetings All,
          When set to bracket style, the spanner seems broken in this passage
which utilizes spacer rests, a cross-staff voice, and a \times
command. In the first two measures, it ends at the fourth beat instead
of continuing to the downbeat of the next measure. The third measure
is correctly engraved. Am I missing something obvious?
          Many thanks for any help.
