Bug with level xp and mastery xp

I don't know if I still got it and it's not reflecting correctly on the match history. Or if I really didn't get it and I don't know why I wouldn't. But I noticed there was a handful of games in my history that either don't have level xp ratings or mastery xp ratings.

Game with no Mastery earned https://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/3105681315/2250142898842176?tab=overview

These are just 2 examples but there's a handful of these I noticed in my history.
