Scammer made good on 3 year old, scam what now?

I was scammed 3 years ago, aprox, for a couple 20$ steam wallet codes for 23 csgo keys @ $1.85 per key. i gave the wallet codes but didn't receive the keys. I was contacted by the seller/scammer a few days ago. Since then he/she has made good and gave me the keys to cover all that was not given 3 years ago.
I have proof he/she gave me the keys, and proof of our recent chats about the issue, etc..

My question is.. what now? how do i help him to get the report cleared on my end?
sorry for my ignorance, but it has been a couple years since i have used this site. thanks for any help pointing me in the right direction. till then i will browse the faq again and see what i can find.
attached is proof of payment and current chat.

Thanks All, for the help.
