Cgs and Cgs vs Vgs

Hi.
I set up this circuit for simulation Cgs and Cgs as Vgs changes.

Below are the curves Cgs and Cgs vs Vgs.
(please see it in the second post. The forum doesn't allow to post two images in a single post)

I have some questions, hope you can help.

1. Why Cgs and Cgs are negative?
2. Why Cgs and Csg are not equal?
Thanks.
