Octave lines are attached to the staff rather than to notes, so when you cross notes to the other staff, they’re no longer governed by the octave line on the lower staff.

Cross-staff notes still “belong” to their home staff, and octave lines apply to the staff. To input an octave line that affects the top staff you need to show the note input caret, position it on the top staff, then input the octave line (you’ll almost certainly need to press Space at least once to give it duration). Alternatively, input one anywhere else and Alt/Opt-click it into place.
