You are descending to fast while still have enough speed to be airborne. You need to flair and level out just above the ground, the plane will come down when the airspeed slows down enough.
Right. The 4-stars land just fine if you do it right. I tell my students to never do anything to try to force a plane to land. Line it up, slow it down, sure, but don't make it land: it will do that all by itself.
