[CLIENT] Grade not appearing post-game

Post-game, in the match stat section of the client, grade do not appear every few games. Where the grade is supposed to appear there is just a loading symbol. Even when I try to check in the match history section, there is no grade that appears.

Even if I try to check my history on the website, a grade does not want to appear.

Even after a couple of days/restarting the client/every other possible solution I can think of, the grade just does not want to appear.
