Request input regarding FMCs installed on some Boeing airplanes that have been reported to delete an associated waypoint speed constraint when the flight levels off at the same waypoint with a climbing altitude waypoint constraint.

Example: SID has a waypoint speed/altitude constraint of 230KIAS/5000'. When the flight levels at the altitude constraint, the speed constraint disappears and the command speed advances to the default 250KIAS/below 10k speed constraint.

Has anyone experienced this issue?
