Step climb deletion

[salokin]

A350 MSFS2020. For today's flight I inserted two step climbs. Upon reaching the first I decided the plane was not ready to climb. Message "Step climb deleted" subsequently seen. But it was the second step climb that was deleted from the list, not the first at the waypoint already passed. Surely incorrect behaviour?

I am not an irl pilot, but I believe that failing behind one step climb or even modifying cruise alt will erase all step climbs atm for the game.
