Why isn’t my diamond badge animated?

So last season, or season 13, I reached diamond both splits in arenas. I did the same in season 12 and got the animated diamond badge for arenas for that season. But now, day one of season 14, I checked my stats which say i reached diamond both splits of season 13, yet my badge isn’t animated. Any clue as to why? (I linked two photos for reference, I circled the badge that isn’t animated.)
