Am I crazy ?

So im building 75396 (sarlac pit and dessert skiff) and I noticed that on step 63 it calls for 3x tall slopes but if you notice on the pic for step 63 they added 4 of them between steps. In the 3rd picture you will notice if you use the number of pieces listed it doesnt look how it does in the instructions. Am i tripping or are the instructions printed wrong?
