Traffic ticket, Ontario, Canada?

I got pulled over for the stickers on my plates on my car being wrong and I only have my G1. They let me off with other charges but I think I got nailed with the $110 for driving with my G1. At the bottom it says Set fine of $85, total payable- $110. I don't know what this means at all because when he was talking to me he said that he would let us off with all the charges.
