all this while it shows me bunches of flights on CM and VS that do NOT have ANY first/bf seat

To be fair, this isn't the operator (CO) hiding that the short segment is in Y. It is NW choosing to display that reward in F even though one segment is not. CO does the same thing all the time with some of their partner flights. I'm actually somewhat surprised that they don't do so in this case, too.
