Again, the problem comes from not being able to identify another force that is involved, which is air resistance.
All objects moving through air, and hence, all falling objects, experience air resistance.
This force is proportional to the area of the object in the direction of motion.
Usually, this force is negligible, but for light objects — with weight comparable to the air resistance, like a feather — it will have a big effect.
This is ultimately confirmed by the famous hammer and feather drop experiment on the moon.
