What are you talking about? I highlighted two issues, two false behaviours, it's not a comparison, the other examples are used as reference only.

The text "S/C" should be displayed in green next to the waypoint where step climb is taking place and it is not the case in this simulation.

The "FIX" menu of the FMC is bugged, one cannot reach it's second (third, etc) page if the first page is not populated.

Don't hijack the topic by calling it a comparison. This is an observation and possibly a bug discovery.
