League of Legends (LoL) Question: Community Tier List Error?

Hello, I'm not sure if this is the place to say it, but I'm having an issue with the community tier list. I no longer can click on the champions and choose their tier, as the number buttons don't show up anymore. I think this is the first time I've tried using it since the website layout has changed. If someone can help me or let me know how I might be misusing it, I'd appreciate it. Thank you.
