Narrative:
Aircraft overflying sju approach at 14000 ft; 4000 ft above sju approach airspace. Computer initiates an 'automatic handoff' to R5. R5 controller inadvertently accepts handoff and computer automatically removes assigned altitude from data block. R2 controller now has no indication on radar display showing aircraft's assigned altitude.
