I owned this same refrigerator for 10 years so am familiar with it.  The shelves and drawers in the new one are not as deep and hold less.  Hard to put bigger items on shelves.  Thought if you got rid of that bulging inside light it would free up the shelves. Do like the new lighting tho.  Ice maker throws some cubes inside the fridge and it’s more difficult to get ice maker in proper spot.
