[CLIENT] Level 6 to Level 7 Mastery Animation Shows Level 5 to Level 6 Instead.

Hello. I'm using the new client and I thought I saw this once, but I didn't think it to be true, but today I definitely confirmed it. When I gain Mastery Level 7 in Hextech Crafting the animation that plays is not the Level 6 to Level 7 Promotion. It is the Level 5 to Level 6, which is sad because I worked very hard being the scum of the earth gathering Level 7 Blitzcrank shards. If that doesn't repulse you then the first time I did it and this error appeared was when I got it with Lux not too long ago. So, it's not a huge issue, but it is a little disheartening not seeing my achievement be recognized and also making me question if I actually did get that achievement for a moment.
