Finer aspects of the /drop command

[Drakeero]

There seems to be a lot of items that don't accept a quantity value in the drop command.

Body parts seem to be one of them. I'm going through the dungeon towards a dungeon warp and seeing if I can drop the body parts I pick up along the way.

So far stuff like wolf's leg, wolf's hand, and food will only drop one at a time even if I put in a number to drop.

Is there something I'm missing or does it really not register?
