System awarded me my teammate's S+

It doesn't register in history as an S+, but in post-game lobby the system awarded me an S+ that belonged to my teammate (the Lux). I'm guessing it does show up in her match history, but she missed out on a Mastery 7 token from the mix up.
I'm hoping, ideally that there's a way to correct this =)
No correction's required for me as I'm not high enough mastery to have earned a token from this, I recieved the standard chest from an "S earned by you or a teammate" and my match history reads fine.
