Boxing/unboxing composite item clarification

Boxing/unboxing composite item clarification

I have created a composite item, and now it is sold out. I want to add 6 more of these to my stock, so I box up the composite item and it says stock is now at 6 on both my sales channels. 

When I look at the boxing/unboxing details for this item it says $-4724.28.

The value of the box is only COGS $8.30, selling for $24.95

Question: what does the $-4724.28 mean?
