Summoner profile Champion sorting bug [CLIENT]

So, I recently changed my champion sorting on my summoner profile to 'Highest Mastery', and ever since I did that it'll show me that same page again even though the sorting is selected as 'Alphabetical' which is kind of bothering me. I've put a link of a GIF where you can see the problem I'm having. Ofcourse, I can change it back again manually by changing the sorting but I don't think that solves my issue. I have tried resetting my client but that doesn't seem to work. I don't know if I am the only one experiencing this but I hope you can help me out with this.
