Champion Mastery

The Champion mastery for my own page is bugged to completely different levels. In other words, it is telling me I have level five mastery of Sona when I dont even own Sona and have never played sona once in my life. It also says I have 0 mastery of J4 When I had level 5 before. Its kind of hilarious I'm not gonna lie but it is a but i feel I should report. I have pictures but it won't let me load them.
