As per the drawing I posted, my MH have only two for each sofa/recliner set but your sofa is bigger, if I'm not wrong, so that would justify Thor the trouble of carving the slide floor and adding a third support.
I think these may be related to the fact that people will be sitting on the sofa/recliner while the slide is in during travel so it needs more support.
I would contact a dealer and discuss with them adding this support back.
