Not getting correct ranked rewards s18

Me and a buddy grinded to master last season together he got his masters rewards but i only received the diamond one as it says my peak rank was d1.  I was higher points then him as well as having a screen shot of me hitting masters in season 18 posted on my steam here on 10/12/2023 during season 18 https://steamcommunity.com/sharedfiles/filedetails/?id=3049856392.    Will I receive the right rewards?
