negative balance

I got payed recently and my balance was 0.
Then I had this in sales:
Additional Revenue from GPP 18.64

And my balance became -18.64
At first I ignored it, but after another sale the balance became -6.14
So, it means the balance is negative indeed.

So, what is this negative "Additional Revenue"?
